Has ANYONE come down with measles near that hotel? And the group has been there "sometime" but not currently? Over all, this is still somewhat rare, and the health dept is all over this, so you would know. Personally, you would never know day to day what you have been exposed to, so you cant live in fear. Also, the vaccine is good if you got a second booster, which you may have, or if you had wild measles growing up.
