While my first post was purely in jest, I'll try to post seriously now. (Pre-trip giddiness has set in...)If $450 is for a regular room, then I think it is just way too much. If it is for Concierge on NYE, then maybe I would pay it. The *maybe* comes in as to whether or not NYE is a super important event to me and mine.
I have only spent over $300 per night at WDW once in my life. That was for my 10th Anniversary. It was concierge at the AKL for 3 nights. To reach 10 years of marriage, still be in-love with each other, and be able to take your wonderfull, loving and loved offspring along calls for a special celebration. I'd pay that again for that occasion in a heartbeat.For me, NYE just isn't that special. If it is for you and yours, then only you can decide.
