You want your Orlando vacation to be special- why let your health get in the way? If you have prescription medication, bring some with you! Many people think they won’t need it, or just plain forget it. Then they have to pay a lot of money when they discover they DO need it after all. You can pack a small bottle to take with you to the parks and leave the rest at your hotel room- if you lose the smaller bottle, you won’t have to replace the entire amount.
If you have allergies, but don’t think you need any medication for it- think again. Orlando has flowers and other plants everywhere, even in December and January. There are also cases of people allergic to latex buying rain ponchos that have latex in them.
If you have insulin, you can often arrange to keep it cool at a first aid station. If you prefer to keep it with you, there are products such as the Frio Cooling Wallet- soak the wallet in cold water for about 10-15 minutes and it will stay cold for several hours.
