Success! My issue has been resolved. I wrote a clear & concise letter to Expedia & emailed it to the execs listed on this site; since my timeframe is limited I sent it to all four of them at once. I also, as some of you suggested, sent that letter to a hotel executive. A hotel exec & an Expedia exec responded, the latter being extremely helpful. She called the hotel on our behalf & had them cancel our reservation & give us a full refund. We had only wanted a change of dates for our booking but if that’s the way Expedia wants to roll, we are happy to roll with them! We are very grateful. The lesson is what some folks on this thread have said: don’t try to save a few bucks by booking through Expedia or the like. But also the lesson is: don’t give up - if you make a goof (like my husband - the lawyer! - did), appeal to the best in others & don’t be afraid to share some personal details about yourself & why the help you seek would mean a lot to you. Thanks again to those of you on this thread who were encouraging & helpful & supportive, especially Chris in NC, jsn55 & Neil Malley and all Elliott staff too.
