Flight.doc(2KB)
Dear Mr. John Davidson,
Regarding the trip to the conference in Jacksonville, Florida, I have looked for flights on the Internet and found out a few possibilities that we could use. You had indicated that you wanted to fly to Destin but that might not be the best plan. Although it is a cheaper flight, we’d then have to take a bus to Jacksonville, which would take a long time. I’d prefer to fly directly to Jacksonville. Also, the morning flight would be ideal. We would have time in the afternoon to see the capital of Florida, Tallahassee. Please see the attachment and let me know what you prefer.
We also need to reserve hotel rooms. The conference organizer informed me that the Europa Hotel does not have rooms available until the beginning of May. It is very disappointing because staying at the same hotel where the conference is being held would be convenient for us.
However, there are other options. Western Phoenix Hotel and Victoria Park Plaza Hotel are within walking distance. If they are full, there is the Corona Hotel. Would you mind arranging a hotel room for us The hotel phone numbers are on the conference web site. We’ll have to reserve 5 days. The conference is from April 26 to 28, but we should try to arrive in Jacksonville on April 25 and leave on April 29.
Best regards,
Peter Plate
