Ok. Report time as far as I am concerned.
First off, the only things changed outside are the color of the building and the new poster. The AT-AT and Ewok village are still there. The outside of Tatooine Traders is still the same as well. Upon entering the building, you notice there is carpet for the first bit of inside queue and the "Hot Set" wall is gone, replaced by a wall that looks like it fits much better. The biggest change in the first room is the screen. No more green squares (something that I will miss). But the new screen shows many ads for Star Tours (the company), arrivals/departure on time info/gate numbers, and (I thought this was a nice touch) a weather report for different cities on the planets Star Tours goes to (more planets than the actual ride goes to). C-3PO and R2 look better than than they did when Star Tours (the original) first opened. Not much has changed with the Starspeeder except the burn marks are gone.
The second room is changed for the better. The droids are still there but one is a baggage checker (you can see inside the suitcases) with some hilarious outcomes and one is a passenger scanner (thermal images but I could be wrong). Rex is in the queue. There is a shipment of Rex's (I believe it is ever Rex from the first Star Tours) and the first one is malfunctioning and every now and then says something from the first Star Tours (no they did not change the voice of Rex) like "I meant to do that, hehe" and "Brakes. Brakes. Where are the brakes?" The rest just sit there.

There is also a window from the previous queue that they now use as a way to show other "flyers" in silhouette form. From humans to Twi'leks (look it up) to a Jedi using a mind trick on a Stormtrooper. Keep an eye on it and you may see something you never expected.
As for the ride, I won't spoil anything as this is the reason the wait was worth it. But I will say that re-rideability is perfect. We rode it 3 times and had different planets each time and I think there are at least 2 other planets we still haven't seen yet. Between planets, a random Star Wars character will show up in holographic form (very cool effect, we got Yoda twice and Admiral Ackbar). We even had two different starting ports with a little something different happening when we got the same port the second time.
Anyway. I'm sure I've forgotten some stuff (or have I?

) Any questions you may have, just ask and I'll try and answer to the best I can.
