We are checking in to Aulani 12/14 for 7 nights in a 2 bedroom lock off, pool view. I had called MS a few weeks ago to request 5th floor. Since I have such a request, should I do online check in, or just wait until arrival and check availaibilty at the front desk? We will arrive a little after lunch. We'll wait to head to Costco until after we have checked in. I really hope we can get a 5th floor villa...I know, just a request. I'm hoping with the opening of Ewa tower that there is more availability. Thoughts?
