Just returned last night. We had a great time,boy was it ever hot!
Tthis was our first time in the summer at WDW, we usually go off season. My tip is when a park has EMH in the evening get up and go to that park first thing the next morning and it will be practically deserted. This trip was DD (18) & I for a long Mom / Daughter pre college weekend. We went to MK on Sat. and rode 7 rides (Sp. Mt.,BT, HM. Sp.Mt.,Stich , Philharmagic & Sn. Wht,) in two hours. We were walking at very leisurely pace stopped for bottled water at cosmic ray's and had several bathroom breaks in there too. We repeated this monday at MGM and same thing, it was great. But one caution at 11:30 when we were ready to leave and go have lunch and hit the pool,the crowds coming in were HUGE!!! I could'nt believe it. Anyway. didn't intend for this to be so long just wanted to say we had a ball and have deceided to make it a annual event- Yes, it was hot, yes it rained everyday, yes, it was crowded but in a weird way thats what made it fun!
