I used on line check in for the first time last trip. They met my request for a room near reception (AKL) and I by passed the normal check in queue which was longer but not very long. We were done in five minutes. It wasn't life changing but I'd do I'd do it again. The on line check in system gives you certain choices to request regarding your room, no space for free text. Or there wasn't for AKL, I've not seen the screen for any other resorts. I will be doing it again but have always had my room requests more or less met at normal check in too although I had to get them to change my room at the Beach Club. That was a fold out bed issue not a location request.
