Hi Bob, the only one we have ever been on is the ship currently run by P&O Australia as Pacific Pearl, ex-Ocean Village, exex-P&O MV Arcadia, exexex-Star Princess, and originally, accoring to Wiki, Sitmar Fair Majesty - boy hasn't she been around.
The bar was never that busy though as it wasn't very side, so you had to either wait for a space, or simply climb out & attract the attention of the poolside waiters.
Will be interesting to see if there are more out there.
