Heard from a CM I could ask at check-in if Concierge level (14th floor) room was available and upgrade by paying cash. She could not/would not quote a rate. Has anyone done this before? Is concierge level really worth the extra $$$? We are traveling with our sons, ages 3 and 5, and thought the convenience of continental bkft, snacks, drinks, (not to mention the view from the lounge) might be worth the extra price. I'd love to hear lots of opinions, especially due to the cost to be considered. Thanks for all your info. this board is great!
