He gave us a room with an ocean view. The airline had sold too many tickets for our flight, so we got to sit in first class. Our good fortune continued at the hotel. We can't wait to visit Florida again. He also gave us coupons for lots of free things. The hotel manager apologized for not having our room ready when we arrived. Our vacation in Florida last month was almost perfect. The weather was beautiful, so we spent every afternoon at the hotel pool. Our good fortune began at the airport before our departure.
