hellokitty,
Here are answers to some of your questions:
1) The basic cruise price does not cover the cost of transfers. They are extra along with airfare if you choose to book that with your cruise (I wouldn't recommend it as you can usually find cheaper airfare on your own, however, I usually buy the transfers just because I think it's a little easier even though it's a little more cost wise).
2) Eating . . . you can eat as much as you want with no limit. The last cruise I went on, my brother, who's a chef, couldn't decide what to order each night, so our waiter quit giving him a menu and just brought him one of each item on the menu that night (appetizers, entrees and dessert)! It was a TON of food, but he loved every minute of it!! Food is available 24 hours a day . . . basically anything, and as much of it as, you want!
3) Tipping . . . this was covered above.
4) Getting Seasick . . . the ships are so huge and stabilized that you really never know that you're on water. When seas are very high (10 - 15 foot waves or more), you do feel a very slow swaying up and down (sometimes side to side). But it's nothing that bonine (or many other products) don't take care of. It's definitely nothing to worry about.
5) As for room location and type, that's really your personal preferance. You need to balance cost with how much "luxury" you want (outside view, balcony, bigger room, etc.). You can't go wrong on ANY room type on
DCL. They're all nice. Just something to think about.
I've been on many cruises. I even met my wife on a cruise in Alaska -- yes, we've had to laugh at all the "love boat" comments over the years. I think that cruising is the BEST way to travel. You get to see many different places without having to worry about driving, checking into hotels, finding restaurants, etc. Not to mention the fact that you are pampered like royalty during the entire trip. I, and probably everyone else on this board, will say . . . "GO FOR IT!!!!" Good luck!
