For my first cruise, a bunch of American spouses living in southern Spain took a girl's only trip. There were 19 of us. I suppose there were other Americans on board, but we didn't see/hear them. There were approx 75% Spanish and the rest other Europeans.
The crew was very friendly and I was amazed at how attentive our room steward was. I wish there was coffee/tea in the rooms, but none was available. Possibly in suites, but not in balcony rooms. The room safe quit working after 2 days and wouldn't lock closed. We had a problem with the on board cleaners, which took 2 days to get clothes back. My roommate really went to bat about not being charged and eventually they agreed. She wore the same pants for 4 days because of that snafu.
The food was great in the Windjammer! Our big party had a certain table each night and the waitstaff were awesome. Only con was being on the ground floor and getting some water spilled on me during one of the events where the cook crew comes out and people stand at the balconies to watch. Had me wary the rest of the time we sat there!
Oceanview Balcony with pullout couch. Closet was a bit small due to safety equipment taking up a fourth of it. Bathroom had corner shower, leaked onto the floor, but enough room to be comfortable. We had room for the couch and coffee table. No gripes at all about the room.
Part of our group of ladies had interior rooms with 2 twin beds. Upon opening the door, you about fall on the bed. No room, but if its price that counts, it's worth it.
Another couple got upgraded to a junior suite. WOW! kitchenette, living room, balcony twice as long as ours. Big bathroom with tub.
