Before getting on the ship, I was tracking concierge availability and they still had 3 V-cat rooms left. To increase our chances, we stayed at the airport Hyatt and used Disney ground transfers. Our plan was to be on the first bus but we ended up on the second. However, I believe the first and second arrived at about the same time. I know there were a few others--I met one of them in the concierge lounge--who had plans to get there early to make a play for the remaining rooms so I'm pretty sure I got lucky as much as anything.
#1. What catagory did you pay for? VGT. I was assigned a 7A but the line on the chart they used to determine my upgrade rate was for VGT not 7A. (The difference between the two appeared to be about $40.)
#2. Which Ship? Fantasy
#3. Number of Nights? 7
#4. Month/Year of Sailing November 1, 2014
#5. What was your Port of Arrival time assignment? 12:30 (meaning, if I hadn't gotten the upgrade, we would have had a loooonnnngggg wait)
#6. What time did you check-in? About 10:15
#7. What catagory were you offered for upgrade? Category V
#8. How much was the upgrade? $1225
I did not check pricing on anything but concierge because the port rates for an upgrade are usually the same as booking the different category in advance. As I've noted before, the real port upgrade deals appear to get better the higher the category, starting with the V cat. Even though the cat T and R were not available, I noted what the costs would have been if they were:
V $1225
T $2975 (I'm a little concerned I got this one wrong; when we upgraded two years ago to T from VGT, it was about $2K. I'm wondering if it was $1975 and I noted it incorrectly...?)
R $3675
In retrospect, I spent a lot of time worrying about getting there early enough, making special arrangements to get there first, and generally being stressed about it. As many others have said, if you're going to try for an upgrade, be absolutely sure that you're already happy with your assignment and that it won't be a big disappointment if you don't get it. Otherwise, just pay the difference up front. And if you're hoping to upgrade to a non-concierge room (and you didn't book IGT/OGT/VGT or similar room that cannot be changed beforehand), then definitely do it before you get to the port. You'll have better options the sooner you do it and it appears you won't really save money by doing it at the port.
Good luck!
