We are headed to Disney for our first trip with the kids next month. They are 6, 4 and 9 months old. I was planning to bring our Snap and Go for the 9 month old because he still really loves to be in his carseat and not the big regular stroller. Everyone has been telling me I also need to rent a double stroller for the big kids. I just had the idea to maybe rent a double stroller with carseat adapter and glider board, so that worst case all 3 could have a spot on the same BEAST. I'm also bringing a baby carrier but the baby isn't a huge fan of being worn.

What would you do?
