I've never used comps before to pay for meals, so I'm sure the best way to do it. I have about $75 in Total Reward credits to use for my upcoming trip. Is it better to just charge everything to my room and pay for it all at the end? Or is it easier to just pay for each meal by having them swipe my card? I guess my biggest concern is tipping, if I charge it to my room do I still need to leave a trip at the restaurant or will the tip get charged to my room as well? If I pay at the time with RC can you use your RC to tip as well or do you have to use cash for that?
