Any of the Voyager class ships.

See my article at
http://candyharrington.com/clips/twi.php

It has been reprinted a numner of times, but it's fairly indicitive of what you will find on any RCI Voyager class ship.

The Monarch is really old and retrofitted -- I would not actually recommend it. You need to look for newer ships -- constructed since 2000 for the *best* access.
