Oh, good grief! I NEVER even thought about that. We did a "drink around the world" trip in April and never once pulled out the TiW card when we weren't ordering food. It just didn't cross my mind. Now I feel like such a big dummy!!! Thanks for the heads up, everyone. I certainly won't make that mistake again!
P.S. - It's so funny how things change over a lifetime. Our first 14 years of trips, we never had a single drop of alcohol on trips... we never drank with the kids around until the youngest hit 18. At that point, we would order wine or beer occasionally with a meal. Once the youngest could join us for F&W events, the trips took on a different hue. I suppose when grandchildren come along, we'll be back to tea-totalling again!
