I have about $220 in RC's. I've read that it's better to pay with your TR card so you don't pay tax rather than charge to your room. Two Questions: 1. Wife and I are doing a couples massage ($350). Can I pay $220 with my RC's and charge the rest to my room? 2. After my RC's are gone from the massage, charging to my room and paying on the spot (cash or CC) are really the same thing, right? Since I'm paying tax either way. Sorry if these questions are dumb...I've never used RC's before. Thanks.
