This was our third time staying at this particular hotel in the last 10 years so we have a history to compare it to. It will be the last time we stay here. For the room price and the options that you have to DEPEND on the hotel staff to provide for you in a timely manner, it wasn't worth it. Nice property to look at though

  • Whether you print it out or use an electronic one, you'll need your boarding pass to get on to the plane. You'll also need some kind of government-issued photo identification. If you're flying internationally, make sure your passport is valid and you've checked visa requirements.
  • Make time fly by even quicker on your short hop by packing the right gear. Think tasty snacks, a water bottle and entertainment. If you want your trip to Index to pass peacefully, put some headphones or earplugs in your carry-on bag too.
