"The hotel is becoming dated. Cracks in drywall, grout coming out of tile flooring, window coverings in need of attention, room door security in need of repair. We were comfortable, but, it seemed like the place was just going thru the motions with no repairs being done."

  • Keep your passport and boarding pass somewhere handy. They’ll be the first things you’ll be asked for by security personnel.
  • Belts, coins and keys are to be put in a bin for X-raying. If you enter the body scanner with any of these items, you’ll be requested to turn back and remove them.
  • All laptops must be taken out of their protective cases and placed in a tub prior to being X-rayed.
  • When you approach the security checkpoint, you’ll be asked to put all creams, liquids and gels in a separate tray for scanning. Make sure they’re all stored in containers smaller than 3.4 ounces (100 milliliters) and sealed in a clear zip-lock bag.
  • Think about your choice of footwear. Slippers are great because they’re super easy to remove when you’re at the security checkpoint. Try wearing some on your next journey!
  • Pack any pocketknives or other sharp metal items inside your checked luggage. Security won’t allow these on the aircraft.
