We (myself, DH, DD7, DD5, DS3) are going to Disney World for 10 nights next summer. The last few trips, we have stayed at the YC and the kids love the pool. This time, we want to go back to the Poly to be on the monorail line, as the kids also love the MK. Has anyone changed resorts mid trip? Is it worth the effort to change resorts with 3 young kids, or should we just stay at the Poly for the whole time?
