Hi Marie
Most of the hotels will have laundry facilities. If you are looking to wash your clothes half way through, the Crystal Inn in Salt Lake City is a good bet. They have a coin-operated laundry service there, so it should be fairly cheap to use. Occasionally we have to change hotels but I'm sure wherever you stay you will be able to wash your clothes.
The Grand Canyon flight costs around £115. You can pay for his in resort in dollars or, I believe, by credit card - this will be confirmed in the letters you receive from us 15 weeks and 2 weeks before departure.
Kind regards
Olly, your editor
