We will be heading to disneyland in a couple of months with our 5 year old. We will be bringing a backless booster seat for him since he will be riding in the shuttle bus to/from the airport/hotel. We will also be taking a taxi to Medieval Times while down there. I'm just wondering what we are suppose to do with the booster seat while we are at Medieval Times? Can they put it somewhere or do we have to just carry it around?
