Dear Dennis,
We just want to say thank you for having us before we caught the plane last week. It was a nice evening, and we enjoyed __ Peter and Sarah. With your help we were able to get to the airport with plenty of time. We often tried to get an  earlier flight (航班) than usual, but it wasn't possible.
We had a __ holiday in Spain (西班牙). We just loved driving through the countryside, and we often __ to walk round a mountain village. We met ___ friends, Bill and Sue, and they invited us to have a meal with them. They wanted us to stay with them. But we couldn't, as we had already booked (预定) two rooms in a hotel. 
The weather was nice. There __ so much beautiful sunshine all time we were there. Leaving Spain was very sad. It made me want to cry.
Anyway, we are looking forward to hearing from you, and hope to see you soon. Let me know if you're ever in the area.  You must call in.
Yours,
Ray
