The skiing and snowboarding is only half of the total fun of the trip. Every trip there are skiers and snowboarders who go for their first time ever. It is possible to recieve free ski lessons at Winter Park. Snowboarding lessons are also available, but usually are not free. If you plan on renting skis then I would plan on having some extra money for that.
Rentals vary from place to place in price.
We can always get very good quality rentals, usually they are brand new skis in the previous year's style. Be sure to take clothing that you can pile on top of as well as peel off a layer when the need arises. Thick gloves preferably with leather palms. It is also important to have plenty of comfortable socks, you will go through these very quickly. Longjohns are definitely a plus.
