Yes, I've booked a couple - one in Barcelona and the Caves in Palma de Majorca. Most of the others weren't very interesting. We will also purchase the unlimited internet package and upgrade to ultimate beverage package (from premium), as well as 3 night specialty dining as soon as we board. I'm thinking perfume and the spa might be good options to spend the rest. Oh such a difficult "problem" to have. Thanks everyone for the suggestions.
