Pardon my ignorance.... I am going to be in Las Vegas with four friends later in the year for 8 nights. We are staying at the Palazzo and will no doubt spend a fair bit of time at the Palazzo and Venetian Casinos. Can someone explain how the comps would work? I understand how they calculate it, but do you need to register or whatever. And as are from New Zealand - we might not be back for sometime, if ever...how do you claim the comps while you are on the trip?
