From other resorts to OKW is not the problem. But if you ever want to transfer from OKW to another resort - make sure and call ahead of time to make sure they do it and if you are told they do, make sure and get a name of the person you talked to. I was changing from OKW to the Swan, I called 2 months before my arrival to make sure they would do the transfer. Was told yes, no problems and I even talked to Bell Services at OKW. When I got there and we were getting ready to leave our room that morning and check out - I called down to bell services, told them we were checking out and would need our luggage transferred to the Swan. They told me they don't usually do that (I was assuming it was to the Swan and Dolphin so I don't know if he meant in general or just to those two) and I told him I called 2 months before my arrival and was told they do it. He said he would do it this time and in this instance and next time if I call to get a name of the person I talked to.
Just giving you an FYI!
