We are a family of 3 - My wife and I are between 45-55 yrs of age and our son 13yr old. We booked a balcony cabin on the Escape in November and were lucky enough to bid (and win) on an upgrade to the Haven (H5) - we were assigned cabin 17128.
On viewing the location of the cabin we were a bit concerned as just on the other side of our balcony was the Ping-Pong area. We were a bit worried that people would be able to look at us on the balcony. I am happy to report that this was not a big issue. During the initial sail away from Miami there were people there but they can only really see you if you are leaning out over the railing. This was really the only time that we had a significant amount of people there.
Prior to boarding we decided that we would be using the ship and not getting off of the ship in any port. We had been to all 3 ports a view times and really had no interest in any of them.
Cabin was great- room for 3 of us.
Large balcony - dont worry too much about the Ping Pong Players
