Definitely do MK: haunted mansion, BTMRR, Splash Mountain, buzz Lightyear, Aladdin, all of Fantasyland, Tomorrowland speedway, meet the characters, watch the parades. There's so much to do I can't name them all! - Jalex239  379.8 #7 12:50PM

A MUST do is The Pirate's League!  It's FUN and so affordable.  He can probably do everything, except a few rides that he might be too short for. - DizneyGirl  354.5 #9 1:46PM

Kidcot & the new Perry scavenger hunt (?) that took the place of Kim Possible at Epcot. - Tinkerbell1265  372.1 #8 8:02PM

Innoventions has some cute hands on stuff thats good for younger kids! It kinda reminds me of a hands on science museum - mkigos  42.5 #77 8:04PM

One hint we made it a family rule for every trip- if you are tall enough for the ride you have to try it other wise you will never know if you like it or not. More often than not they love it and want to do it again. It might be easier to get your hand on some maps and highlight for them the have toos or get on computer aand make with them their personal maps. 5 is such a great age and there will be alot he can do. Have fun helping them plan - mmddgp  178.2 #28 11:52PM
