Yes, we are fine with whatever inside room we get. It was nice to save some money and feel like we have a bit more to spend on things like adult beverages, spa, souvenirs and the like. I also agree that there is no rhyme or reason to upgrades. I honestly wonder if they randomly generate a list of passengers/parties and then look at what that party currently has and see if they can arrange an upgrade or not. I doubt they put too much work into figuring out how often you sail, when the last time you sailed was, are you DVC or CC or which level, etc. That could be a lot of work.
So, to the person who asked about in-port upgrade. I have been researching it here on DIS and here is what I know:
1) You can't count on it, because if the ship is full or there are no nicer rooms available, there will be a sign saying there are no upgrades on the cruise.
2) You want to get to the port as soon as you can to check in, then get in the upgrade line.
3) If upgrades are happening, then each time someone moves up, it frees up the cabin they had for someone else to upgrade to.
4) The price REALLY varies, and no one should count on anything, but IN GENERAL, the cost is 1/3 to 1/2 of the price difference between the cabin you booked and the cabin you want.
5) Also, the price is the same regardless of your family size, so it is an even better savings for those with more than two adults in the room.
6) If you booked a GT category (I, O or V), the base price is the lowest room you COULD have been assigned to and not the one you were actually assigned to. (Though this is the most confusing part and there seems to be some disagreement on the DIS about this.)
7) Basically, you get in line and the CM shows you a chart with what it would cost you to upgrade to categories above what you have and you decide if it's worth it to you or not.
My feeling is that it never hurts to ask and see what the price is. Some people have upgraded to the really nice suites. For us, personally, of course I would love something nicer than a 10 or 11, but we just want to go on this cruise. We paid what we feel we can afford and were thankful for the IGT.
Right now, the economy still isn't great, we have en election coming up and that always affects things, and DH's company may ask everyone to take a week off without pay. So, we'll just sit tight with our IGT.
But, by sailing time, things may have improved all around and we may feel we have the funds to splurge on an upgrade, if one is available. And if not, there are plenty of other ways to spend money on the cruise!
. 33 yrs ago yesterday, DH and I met (blind date), and 32 yrs ago 7/9, we made it official (in St. Thomas while on our first cruise, the Carnival Festivale). That was before people were really doing destination weddings, so we thought we were really being different! Great memories 
.
(exactly what we want). DH must watch the Coney Island hot dog eating contest, or his day will not be complete. We'll catch the fireworks on tv tonight, but it will feel good just to relax.
Here's hoping you pull the trigger and book the cruise!
