Pros
Working on mountain. Lots of variety to the job. Young and energetic coworkers. Company is actually committed to making customers happy. Vail does a good job of giving fringe benefits to it's employees. You may not get stock options or paid vacations but you are going to get a ski pass, big discounts, and free fun activities to keep you busy. Get to meet lots of interesting people from around the country and world. Spend time out doors not cooped up in the same office all day. Have some freedom in how you do your job.
Cons
VERY poor pay. Long hours and mandatory overtime days sometimes back to back. Work all holidays, nights, and weekends with no balance for family life. Poor commitment to employee health and safety. Basically you get hired for the season and they want you there every minute of every day that they can get you. You pretty much know this going in however and your vacation/break comes when the snow melts. You are going to work very hard for very little pay compared to the cost of living in the mountains. If you have a family it can be hard being a seasonal employee because you are not going to necessary have a stable time off to enjoy where you are living. The management doesn't seem to care if people are sick or not and force people to come to work anyway, even if it means literally infecting everyone else around them.
