We have the Deluxe Beverage Package for the Liberty of the Seas out of Galveston. We'd like to know where we can get alcoholic beverages on-board on Day 1? I've read that Texas laws prohibit the sale of certain beverages until day 2. What drinks are also available on Day 1 of the cruise? Is there a limited beverage menu? When we called RC, the person we talked to was very vague in her response.
