We sailed on Pride last March, she's a beautiful ship. Ditto on the other replies, 2 formal nights~suits or tux for men,ladies~cocktail dress or gown and they should bring a sweater or wrap~ the diningrooms are cold IMHO. Your baggage gets checked at the curb. So far we have had no problems with bringing a couple of (plastic) bottles of liquor in our checked luggage, don't put it in your carry-on.
Enjoy your cruise, you will love the Pride...some people think the decor is a bit overboard (no pun intended), but I loved it!
