Hi Cheryl ! We are just back form the World with our 4 yo DS. It was his first time. I kind of regret not taking him earlier (especially since we only live 3 hrs away). He was a pretty fussy baby, but I think he would have been fine. I catered to him too much and now that all my friends are on their second child, I see how much happier these babies that have had "no choice , but to go with the flow" are! If you can afford it, I would definitely stay at the Poly, GF, or CR. It's so worth it with a little one! I would get up very early (all babies do anyway) and hit MK. Then when baby is getting tired, start heading back to the resort. By the time you've strolled all the way to your room, he might be asleep. I would then park the stroller and just let him sleep, if moving him would wake him up. You and your DH can then nap or take turns walking around the resort or swimming (that will be a great break for you guys!) Epcot was wonderful in the evening with our 4 yo. Have a relaxing dinner (Garden Grill was the best) and then take in the parade. TOD is beautiful!!! Relax! You will have the best time and YES, stay on the monorail!!!!
