This was our first cruise, my wife and I, and it was fantastic. The Glory is a very beautiful ship that offers everything you can imagine. You can do pretty much as much or as little as you desire.
We had a balcony room and I could never imagine cruising in any other cabin. They are definitely worth the additional charge. VERY relaxing and beautiful. One good piece of advice I read on another review that I took advantage of was to bring a bungy cord in order to hold the balcony door open. Great for listening to the ocean while in bed.
I have read some negative comments and I also heard some negative comments while on board by a few people. The way my wife and I chose to look at it is hey, you can find a negative in anything you do but why do that.
