Most people who come to the Utah mountains experience a period of altitude adjustment. The symptoms can include headache, nausea, vomiting, and sleeplessness. These symptoms are referred to as Acute Mountain Sickness.

The acute symptoms usually occur during the first eight to 24 hours at high altitude. If you develop a throbbing headache in the sides or front of your skull and it's usually worse in the morning or after exercise, you're suffering from altitude sickness. If your appetite is poor, you can't sleep well and you have no energy, then you are probably suffering from the altitude.

Getting used to higher altitudes usually takes three to seven days. The best things to do are drink lots of water and limit your alcohol consumption. Get lots of rest and take Tylenol or Ibuprofen.

Children should be given lots of fluid. Don't worry if they don't eat very much, but force the fluids and let them get a lot of rest.

Child-care Workers--If you have ever tried to keep children occupied on vacation, you will understand why $2-$5/hr. for 3 to 5 hours of sitting is appreciated.

Concierge--Tip for special services such a making restaurant, activity or other reservations. The amount of the tip is generally dependent on the type and complexity of services provided. $2-$10 is standard range. You may elect to tip for each service, or in one sum upon departure. If you want to ensure special treatment from the concierge, you might consider $10-$20 or more on arrival.

Food Delivery--Don't forget the pizza delivery people or the ones delivering from other restaurants. Anywhere from 15-20% of the pretax total is suggested.

Maid/Housekeeper--Maids are often forgotten about when it comes to tipping because they typically do their work when you are not around. For stays of more than one night, $1-$2 per day is sufficient, depending on how messy you are. The tip should be left in the room in a marked envelope.

Massage Therapist--15-20 percent is customary.

Shuttle Drivers/Taxi Drivers--$2-$3 is usually satisfactory, more if he/she helps you with your bags and/or takes special steps to get you to your destination on time.

Ski Instructors/Balloon Pilots/Snowmobile guides, etc.--If you had a great time, 15% or more. Really at your desecration.

Waiters/Waitresses--The usual 15 percent for lunch and 20 percent for dinner is normal if the service has been good. The tip should be based you your pre-tax total. This also applies to room service.
