I would like to throw a wrench in this.
My ILs are doing a triple split stay during our upcoming trip, while we are only changing resorts once. I received our documents a couple weeks ago and everything pertains (as I expected) to just the Pop Century (package) part of our reservation. We booked AKL room only, so didn't receive anything for that. I booked online.
My MIL, however, called to book and her documents are different. Even though they are also switching resorts, their package info shows the dates for the entire stay--not just the first resort. So I am wondering if the CM at the call center linked her reservations together or something? I had never heard of this.
