I currently have booked a Wilderness Lodge 2 bedroom for October 17-24 but want to waitlist a Grand Floridian 2 bedroom for October 17-21. (Right now, only the 17th is unavailable.) On the waitlist page, do I check the button that says replace my reservation, or will that cancel my entire wilderness lodge reservation meaning I would be homeless the 21-24? I would like to do a split stay betewen the two.
