Have a room at Cambridge Massachusetts doubletree March 12-13,2020. Used points for the one night. This morning March 11, 2020 Cambridge became a hot spot and our events were canceled! American Airlines had no problem with giving us credit and no fee to use those dollars! Want Hilton to put back my points in my account but neither hotel or customer service will agree. US not yet on their list of problem areas. Not acceptable! HELP.
