We went into this having read and researched a lot so we got the cheapest inside cabin (got upgraded 4x though to the top category of inside and deck 11 which was nice) and treated it as a floating hotel. Some information I would have found helpful/passing along to future cruisers...
Hertz has shuttles from the airport to the cruise terminal at 230pm and 4pm on cruise days. We had just missed the 230pm and too excited to wait so took a cab instead, we were in the terminal by 330pm and it was not busy. Called x5101 once on the ship and in cabin (4pmish) and had just missed getting chef's table spots. First on wait list but no cancellations our week but they do happen fyi and it was Thursday night on our cruise which was Kauai.
First night casual wear is accepted in the Liberty and they have the same menu in Liberty and Skyline. Husband did bar hop - $15 for 5 drinks and I went to port shopping/spa raffle session and in hindsight should have done the bar hop. Prizes were good but shopping isn't really my thing although I did learn a few tips.
Quiet, great location on deck 11 so easy access to elevators, pool area and straight down stairwell to shows. Typical inside cabin but we were only in the room to sleep honestly.
