The support from staff was very good. The shower and shower curtain was sub standard. The bathroom floor would flood, since the curtain would blow out, and shower was difficult to control. Some difficulty getting HDMI connection to TV from my computer, though good support from hotel staff.

Being next to the train tracks, I was worried it would be noisy, but there's no crossing nearby and the low rumble of the freight trains was barely noticeable. The hotel and room was modern, clean, and well-kept. The staff were friendly and the distance to the convention center is easily walkable. The kitchen was well equipped with a large fridge, two-burner induction hot plate, pots, pans, plates and utensils as well as a dishwasher. Would happily stay here again.

How to book the cheapest flight to Fort Irwin?
With some of the most exciting flight deals around, you can jet for less with Orbitz. The following pointers will help you land cheap flights to Fort Irwin — and leave you with more money to play with:

  • Departing from or arriving at other airports can help you save on airfares. Enter your preferred departure and arrival airports. Next, select the 'Nearby airports' function below the form fields to see what your options are.

  • The early bird catches the most rewarding savings, so book your tickets the moment you know your travel dates. The cheapest airfares are quick to sell out and prices normally rise as the departure date gets closer.
  • Bundle your flights, hotels and car rental into a competitive package deal. Save your money for things you're really excited about, like discovering every corner of Fort Irwin.

What do I need for the flight to Fort Irwin?
There's nothing as exciting as jetting somewhere new, but it's smart to be prepared. This list of practical tips will help get your journey off to a good start:

  • Whether you print it out at home or use an electronic one, you'll need your boarding pass to step foot on the plane. You'll also need some form of government-issued photo identification. If you're traveling internationally, make sure your passport is valid and you've looked into visa requirements.
  • Make time fly by even quicker on your short hop by packing the right gear. Think a water bottle, snacks and entertainment. If you want your journey to Fort Irwin to go nice and peacefully, throw some noise-canceling headphones in your carry-on bag too.
  • Even if you're flying when it's blistering hot, carry a sweater on board with you. Cabins are notorious for getting downright chilly.
