I sailed the Grand Princess many years ago and I really liked the interior of the ship and I believe it was the largest ship I had sailed at that time.
The outside wasn't the greatest but still had a better look than some of the ships that are now being launched. i.e. Norwegian Epic. (On the outside, that is one ugly ship IMO)
I'm sure the Grand will look much better once the "Shopping Cart Handle" (Skywalker's) has been removed.
