Hi, Kelley!
Don't panic! We are here to help you out. First things first: Where to stay.
For the number of people in your party, I would strongly recommend the
Cabins at Fort Wilderness. Each Cabin accommodates seven people: there is a double bed and a set of bunk beds in the bedroom, and in the common area, a Murphy bed and a couch. Be advise,d though, that there is only one restroom per Cabin.
As a Moderate Resort, Fort Wilderness offers a
host of amenities: among them, a newly renovated pool, a playground, loads of outdoor activities, and, of course, the famous Chip'n'Dale Campfire Singalong, held every night.
Weather in June here in Florida is not as awful as many people think. It's not yet terribly humid, the daily downpours aren't yet fully realized, and the temperatures, while undoubtedly warm, are not blazing. A nice perk to staying on Disney property is that you do have the option of heading back to your home Resort for a swim or a nap during the hottest part of the day. That break really does refresh everyone and gets them ready for an evening of excitement.
The two necessities are water and sunscreen, both of which are readily available at Walt Disney World. Keeping hydrated and sunblocked will help your traveling party stay comfortable, even if the temperatures reach highs in the low 90s.
When you go into a summer trip armed with the knowledge that yes, it will be warm, and yes, you will need breaks, I think you will be equipped to handle the heat. Just remember that breaks during the day are practically a necessity: swimming, rest, and cold drinks poolside can truly work magic on a weary vacationer!
Stay cool and have a great time!
See you later, celebrator!
