This will be our first trip onsite and we've never been to the resort we're staying at (ASMu) and I'm wondering how much of a difference what room you have is? We're are two adults and I think my only preference would to be close to the bus, but again, does it make a huge difference? Is it big enough that the walk to places like the bus/pool really differs? Thanks! Eta: I'm also wondering if we would benefit from online check in, since I don't have a huge preference of where we are and want to head to the parks ASAP. Well be arriving around 11am.
