1.) You are talking about limit poker...
On my last cruise they spread a 5/10 and a 10/20 limit game.
on a 10/20 game your blinds are 5 and 10. you can only do $10 pre flop and on the flop. $20 increments on the turn and the river.
Its more of pot odds, so a lot of time you are going to be calling just because of the equity in the pot.
My suggestion on the cruise, is play like an fn maniac, because most people dont know what the hell they are doing
I would suggest picking up a copy of Super System 2 and read the chapter on Limit poker by Jennifer Harman.
