we were on the 3/23 cruise, and the the adult pool was always crowded. the only way we got lounges was when someone was leaving, and they would offer them to us. people were getting up at 7:00 a.m. and earlier, leaving their stuff on lounges to "reserve" them. it was pretty much dog eat dog, and i'll bet it was even worse at the other pools. its bad on the lst two days at sea, because folks just want to lay in the sun and get tanned. all of the pools are small because they have to be: people could get hurt sloshing around in a large pool in bad weather. terp, we saw some older teens at the adult area, and no one said anything. as long as they are well-behaved, i do not think anyone would complain, especially if they are older teens. there are some lounges on deck 10 above the adult pool area that we had better luck being able to use. and its not really a secret area anymore, but there is a small area at the end of deck 7 that has a few lounges and chairs.
