Our flight from Kelowna was 5 hours delayed. We missed our connection. We were able to get to a hotel by 3:00 a.m. but the breakfast cost us $40. The hotel was good. We were rescheduled for the flight the next night when it was canceled. There were no hotel vouchers available which didn't matter because there were no hotel rooms available. We decided to just drive which was not easy doing a one-way rental to the United States. Worst possible trip I've ever had
