we go in june alot...we'll be there from the 8th-24th this year...
THE WEATHER:
it will be hot & humid in florida in June: period! like others have said: drink plenty of fluids and take advantage of early morning and late evening touring. wear light clothing and take breaks during the "heat of the day" if possible to recharge the battieries. we have found it best to wear comfortable tennis shoes while at the world. we prefer shoes that are "breathable" and prefer the nylon type as opposed to the all leather type(they dry faster and stay cooler)...p.s. if you're the type that will buy new tennis shoes for your vacation; I suggest wearing them at home for a couple of weeks first to get them broke in before your trip; your feet will thank you...june is the rainy season in florida and you can expect periods of rain most days ranging from the daily "afternooners" which are usually 30 minutes or less to the occasional all day type showers. do not let this ruin your trip! grab a poncho and go...as others have stated: this can actually be a great time to tour and enjoy as it tends to clear the parks out somewhat; especially the water parks. as far as the ponchos go: we get the cheap little ones from wal-mart that come in their own little plastic bags; when it stops raining, we just shake em out, fold em up, and put them back in their bags and then put them in a larger zip-lock type storage bag and put them back in the backpack or camera bag.
THE CROWDS:
we have found the crowds in june to be moderately heavy, but with the use of EMH and Fastpass; extremely manageable...I think the best advice I give is: get there early! take advantage of EMH if you can; especially for the fantasyland section of the MK if you have little ones....this place will be a ZOO by about 10am on most mornings.
same for the water parks...either get there early(as close to opening as possible) or wait until after 3pm or so to go...from about 11am on, the water parks can get very crowded and many times will close for being at capacity around noon and usually they will re-open around 2-3pm as people as starting to clear out somewhat.
FANTASMIC:
this is hit or miss....the only ways to get into and get a good seat for the first showing is to get in line early(at least 45 minutes, but preferably an hour or so before showtime) or to do the fantasmic dinner package.
CAUTION: some have suggested having one person holding a spot in the line while others in the group do other things in the park: the line for fantasmic is an extremely long one and it can be very difficult to find or locate the other members of your group if you seperate. also, they start loading the theatre for the show quite a while before the show actually starts. this creates two problems in this situation: 1)the line starts moving, making it very difficult for the rest of your group to catch up or find you and 2)the cm's will chain off the entrance to the line when enough guest have passed through to fill the theatre to capacity...if the rest of your group tries to enter after this, they may not get in...just something to be aware of...
Our best success has come with catching the second showing of fantasmic when they have one...it is usually far easier to get in then.
Overall, June is a great time to go to Disney....It will be hot and crowded, but, just remember to pace yourself, take advantage of the tips here on the DIS, and remember your on vacation and you will have a great time....
Oh yea, I almost forgot: The bus transportation is really good at disney for the most part. we have stayed at AKL before and the buses were fine....we do drive our own car alot while at WDW because we park-hop and resort-hop alot and have found that we can save time driving own car alot of times(especially for the resorts and the non-major park attractions at the world). If you don't have your own car though, don't worry, you'll be fine....If you do have a car; the only park that I don't suggest driving to is the MK. disney transportation is much more convenient IMHO for the MK...also, AKL is an awesome resort!!! the pool is large and never really has seemed too crowded any time we've been there....hope some of this helps...have a great trip!!!
