Our baby will be 4 mos. old on our trip to Disney and not able to sit up. Do you know if I can bring her into CRT with the stroller. I also have the infant seat that attaches that I could remove and bring her in. But it would be difficult to board buses ect. and have to detach the seat to fold up the stroller each time. I would rather just bring her in the parks with just the stroller. But if I can't bring the stroller in then I guess it would be nice to have the carseat to keep her in. We are also planning to each at Ohana's, Chef Mickey's and Hollywood and Vine. Any opinions would be appreciated.
