Can anyone answer these questions about my cruise on the Disney Dream?

1) Are towels provided for sunbathing and at the pools? How does this work? I heard there is some sort of deposit?

2) I know there are "beverage stations" on the ship. Should I bring some sort of travel mug? I also read in a review that you can get bottled water FOR A FEE - that seems ridiculous to me. Do they charge for bottled water like they do at the parks?

3) At Castaway Cay, I know there are free lounge chairs on the beach - but are there free umbrellas?

4) At Castaway Cay, are there lockers? Free lockers?

5) Do any of the rotational restaurants have any tables for just two people. I know Palo and Remy do, but at the other restaurants can you get a table for two?

6) Are there rental fees for the games and equipment for things like ping pong and shuffleboard?

7) I have read conflicting information about dress code in the rotational restaurants. Can a person wear shorts? Can a person wear jeans?

Any help will be appreciated.
