I want to split up our trip into 2 resorts and am looking at starting with a value, Pop Century for 4 or 5 nights and then finishing up at a moderate, either Riverside or Caribbean beach for 2 or 3 nights depending on how my budget plays out. We will be reliant solely on WDW transportation, so how difficult is it to make the transfer and will they transfer your luggage for you while you tour? And do we have to be out of the first resort by 11 am and then not allowed to check in at the other until 3 pm? How does this all work exactly? Thanks!
