We did Pop the first night of our Thanksgiving week stay and asked that our bags be transferred to Beach Club Villas the next morning. Bell services at Pop said just leave it in the room and head out. Several people told us that was ok so we did it. We even left a note on the bags saying they were to go to the Beach Club Villas with a tip. At 9:00 pm, our bags were still nowhere to be seen. After several phone calls to bell services, they figured out that Pop sent our bags to Carribean Beach instead. They then kept telling me it was taking some time to figure out who at BCV would be going to Carribean Beach to get our bags, blah blah blah. We did get our bags back that night but as far as I was concerned, the bell staff at Pop, Carribean Beach and BCV were all at fault one way or another. By the end of the night, I was talking with the night manager at BCV, who was very nice. He listened to my story patiently and apologized, saying they do this all the time without a problem and I shouldn't be worried about doing it again. He also recovered nicely with a few surprises in our room a couple of days later and a generous credit on our folio. I would rather have had our bags at a reasonable time, but it did work. I think the suggestion to stay with the bags or take them to the bell services staff is a good idea. That way you can double check the paperwork. I left a very clear note, but they went the wrong way anyway. I wouldn't let it keep me from staying at two different resorts, I would just follow my bags for the handoff.
Have a great time! Pop was quite nice for the price!
