I have read on here that some members ended up not having to move rooms so maybe you will get lucky.
We use the DDP and I would rather move rooms then have to take it for the entire stay. For us, we did a split stay this summer, moving was not that big of a deal.
I think if you are someone who buys a lot of groceries and does a lot of eating in the room (which means you are probably not on the DDP anyway), moving could be a hassle. For us, it really was not a big deal. We rent a car so all our things were with us.
And, we are usually in the park during the afternoon, so not having the room was really no big deal.
