Split Stay-Campgrounds and Contemporary Logistics

Hello all. We’re planning on heading to WDW in August and in order to make both kids’ dreams come true, I’m considering a split between the campgrounds (renting an RV) and then switching to the Contemporary for the last half. This would be a 9 o 10 night stay. My question is about getting our luggage over to the Cont. after FW. Anyone have any experience with this process? We’ve done splits before but have never stayed at FW.
