Most vacation sick days in Central Florida come from a short list: too much heat and sun, not enough water, a stomach bug passed around the rental, and minor injuries from long walking days. The short answer is to plan the day around the heat, drink on a schedule, respect the afternoon storms, and never take your eyes off kids in the pool. This is general information, not a substitute for a visit.
1. Plan the hottest hours indoors
Summer in the Four Corners and ChampionsGate area means high heat and humidity. Full sun on open pavement feels far hotter than the shade, so the timing of your day matters more than the forecast high.
- Do the rides and long walks in the morning and evening.
- Take a midday break back at the rental, a hotel or an air-conditioned show.
- Check the heat index in the forecast each morning and plan the outdoor hours around it.
2. Drink on a schedule, not by thirst
Drink before you feel thirsty. For moderate activity in the heat lasting under 2 hours, CDC workplace (NIOSH) guidance is about 1 cup (8 oz) of water every 15 to 20 minutes, and generally no more than 6 cups an hour. If sweating goes on for hours, it suggests a sports drink with electrolytes.
Light yellow or clear urine is a simple sign you are keeping up. Refillable bottles make this cheaper at the parks. More ideas are in our hydration tips for theme park days.
3. Use sunscreen the way the label means it
The American Academy of Dermatology recommends a broad-spectrum, water-resistant sunscreen of SPF 30 or higher. Most adults need about 1 ounce, roughly a shot glass, to cover exposed skin. Reapply every 2 hours and right after swimming or sweating. Late morning through mid-afternoon is when the sun is strongest.
See the best sunscreens for Florida heat for how to choose one.
4. Get indoors when thunder starts
Summer afternoons in Central Florida often bring fast-building thunderstorms. The CDC rule is short: when thunder roars, go indoors. Safe shelter means a home, office, shopping center, or a hard-topped vehicle with the windows rolled up.
It also says to stay away from pools, lakes, open parks and golf courses during a storm and to wait at least 30 minutes after the storm before going back out. That applies to the rental pool too.
5. Watch children in the water every second
Many vacation rentals around Davenport and Kissimmee have private pools. The CDC says more children ages 1 to 4 die from drowning than from any other cause. Its advice:
- Name one adult to watch the water closely and constantly, with no phone, reading or alcohol.
- Use life jackets for weaker swimmers. They reduce drowning risk while boating for all ages and skill levels.
- Know whether the rental pool is fenced on all four sides. The CDC recommends a four-sided fence at least 4 feet high.
- Skip alcohol before or during swimming and boating.
6. Wash hands with soap, not just sanitizer
Norovirus, the classic stomach bug, spreads fast in shared spaces. Hand sanitizer does not work well against norovirus, so treat it as a backup, not a replacement for soap and water. Wash before eating and after the bathroom. Anyone who has been sick should stay out of the kitchen for at least 2 days after symptoms stop.
7. Use insect repellent after sunscreen
The CDC recommends EPA-registered repellents with DEET, picaridin, IR3535, oil of lemon eucalyptus (OLE), PMD or 2-undecanone. Apply sunscreen first and repellent second. Do not use OLE or PMD products on children under 3. Around dusk near lakes and retention ponds, long, loose sleeves help too.
8. Pack medicines the smart way
Pack prescriptions in their original bottles, bring your health insurance card, and add a small first-aid kit. Check TSA rules for carrying medicines and devices on the plane.
Once you arrive, keep medicines out of the car. Medicine belongs in a cool, dry place, and a parked car in a Florida summer is neither. See our first-aid kit checklist for what to bring.
9. Never leave anyone in a parked car
A closed car in the Florida sun heats up to dangerous levels within minutes, even with the windows cracked. With new routines and a car full of gear, vacations are when mistakes happen. Put your phone or bag in the back seat so you check it every time.
10. Break in your shoes before the trip
Park days can mean many miles of walking on hot pavement. Bring shoes you have already worn for long walks, a spare pair of socks, and blister bandages. If a blister opens, wash it, cover it with a clean bandage, and watch for redness, warmth, swelling or pus, which are signs of infection that need a provider.
11. Go easy on alcohol and sugary drinks on hot days
Poolside drinks and giant frozen sodas are part of many vacations, but they do not replace water. The same CDC workplace heat guidance advises avoiding alcohol and drinks high in caffeine or sugar during long hours in the heat. If you do have a drink, pair it with water, keep it for the evening after the sun is down, and never mix it with pool time for the adult who is watching the kids.
12. Know where you would go before you need it
Save the address of a nearby urgent care and the closest ER in your phone on day one. Along US-27 near Four Corners, Elon Health Urgent Care (43378 US Highway 27, Suite A, Davenport, 863-282-2082) is open Monday to Friday 8am-8pm and Saturday and Sunday 9am-5pm, with walk-ins welcome. It serves visitors from ChampionsGate and Four Corners. If you are on an out-of-state plan, call to check coverage. Self-pay pricing is available, so call for current rates.

When to skip urgent care and call 911
- Chest pain or pressure, trouble breathing, or stroke signs such as face drooping, arm weakness or slurred speech.
- Signs of heat stroke: confusion, slurred speech, body temperature above 103°F, hot red skin, or passing out (NWS).
- Anyone pulled from the water who is unresponsive, not breathing normally, or coughing and struggling to breathe.
- Severe bleeding, or a head injury followed by confusion, repeated vomiting or unusual sleepiness.
- A baby under 3 months with a fever of 100.4°F (38°C) or higher: go to the ER.
For heat exhaustion (heavy sweating, cool clammy skin, dizziness, nausea, headache), the NWS says to move to air conditioning, loosen clothing and sip water, and to seek immediate medical attention if the person vomits, gets worse, or symptoms last longer than 1 hour.
