Welcome aboard Cruise Mates!!
First, I would definitely suggest talking to you travel agent who is hopefully a cruise specialist and has been there so they can help answer all your questions and find you the best cruise based on your needs.
With that said, there are only a very few luxury cruises that include complimentary booze and excursions. But those are fairly expensive. Some cruise lines have beverage packages that you can buy, but those aren't cheap either.
There are some wonderful river cruises if you think that might be something you want to consider.
But as for which cruise line, that's a personally thing and you'll get as many different answers as there are people - everyone likes something different and what one person loves, another will hate. And what one considers to be a good price/value is very subjective.
And as for 'free airfare', nothing is free! What gets me is that if you ask what the price is with free airfare and then ask what the price is without the free airfare, you'll find it cheaper. Well, if it's 'free', then why is it cheaper if you don't want the airfare??? Almost always, it's a better deal to book airfare independently of the cruise.
It really depends on where you want to go, how long you want to go, what you want to see, and what your budget is. Obviously, that's something you really do need to talk to your agent about as they can be invaluable in helping you gather information.
