I haven't yet been to Wasabi but I wanted to this year despite hearing mostly bad things. I originally planned to be in the artist row, and back in... November, I think (my memory might be failing me, but it was definitely a while back) I checked and was disappointed to see that the artist row had already been filled. They provided an email address to contact if you were interested in getting on the waiting list, but when I did so I never received any kind of response. I wasn't too happy about that.
As I said, I haven't been so I can't give a personal opinion, but my sis and her friend who went, as well as some other friends of mine, all told me they had a terrible experience with the Hotel staff. My sister, her friend, and her mother weren't allowed to check in till 3 pm for some reason (which sucked because they got there at 9 am and really wanted to get into the room), but when 3 finally rolled around they were told they'd have to wait another hour. The mother explained that she had serious knee problems (which she does) and that she HAD to lay down soon because sitting in the lobby was killing her. They let them in. My other friends experienced plain rudeness from the staff, being told to "be quiet" when they were talking normally as they walked out of the elevators, and maids waking them up in the morning despite having the "do not disturb" flaps on their doors.
As for me, from the things I've heard I hope they find a better Hotel. I will probably go next year, but don't think I'll buy a pass or a stay in a room.
