This was the first time we cruised out of Miami - all of our cruises have been out of New Orleans. The Miami port was huge compared to New Orleans - but still very manageable. We had no problems with checking in although friends of ours were delayed because they were routed to see the nurse- anyone reporting an illness, cough or fever had to be checked out by a nurse before coming on board. Luckily our friend just a nagging cough and no fever, so was cleared to get on the boat.
I thought Glory was a beautiful boat - I was a little worried because it is a little older, and I hate to see a shabby ship, but it was nicely kept and for the crazy decor that Carnival is known for - it was really pretty. Everyone that we encountered of the staff was very nice. My husband had to leave his diabetic medication at the purser's desk for refrigeration and they were great every time he needed something.
Our cabin had a balcony - a small balcony but big enough for 2 chairs and a small table. The cabin was nice - bathrobes were provided, but our room was a little warm for the most of the trip and the robes were just too thick to want to wear. The room wasn't unbearably hot -but I would have loved to have had a fan. Our friends travel with a small fan and I was so jealous of them!
