Nice pics!! Looks like a fun trip.
We've gone to Disney a few times in the summer. I guess my fam. is use to the heat since they live outside of Orlando now. If you know what to expect and stay cool you'll be ok. If you plan things out and hit the inside rides during the hottest part of the day that helps too.
minDyG - I think my mom use to wait till we were 3yrs old before she felt we were old enough to appreciate a trip to Disney.
