Have had one excellent trip to Spain with Senior Discovery Tours but have tried a few times to book other tours but have not been successful. Once, the tour was cancelled because not enough people signed up for it, the second time we were talked out of it by your agent, and a third time the tour was cancelled. We would like another tour with your company, but so far have not had much luck. We prefer one stop and stay holidays. Also, we like to cruise but Senior Discovery Tours offers only Princess Cruises. We prefer Holland America or Celebrity cruise lines.
