Over the past three years I have started six of my seven grandkids skiing (this year ages 8+,6+,5,5,3,and 3. The two three year olds had a great time learning, one actually "skiing" to the bottom of the basin at Snowshoe. I put the two young one in private lessons each day, after all they were only 39 months old. One is now a ski "nut" and can't wait to go again. The 8 and 6 year olds were in their third year and enjoyed 1/2 day ski school lessons, both can now ski the black diamonds on the basin side of Snowshoe. The two 5 year olds were in ski school and a private lesson, on skis for their second year (usually only ski one or two trips per year for a total of 5+ days). Both could ski the greens and some blues to the bottom at Snowshoe.
Their parents were thrilled and amazed by their new ski partners!!
The point of this is to caution you that your primary goal with the kids is for them to have fun and want to get back on the snow again and again. They will tire easily. Be sure to put them in ski school, perhaps with the younger having a private lesson each day and the older one in with his peers in the half or full day ski program.
The advantage of going mid week is fewer small ones learning to ski, sometimes a class lesson turns into a private or semiprivate lesson simply due to a lack of other learners.
A potential disadvantage to midweek at some of the farther resorts, such as CV, Timberline, Wisp and the Shoe is a lack of instructors. After the crowd left from MLK weekend my grandkids had things pretty much to themselves and we found two absolutely fantastic instructors: for the 3 year olds all five private lessons were with XXXX and she was great, especially with two clingee kids who are rarely away from their parents. After the first day they were really looking forward to their time with XXX. The two five year olds met an instructor named "Goncho" and he also related well to them, making them very excited about skiing.
In other words be picky, tell the ski school director exactly what you are looking for from the lessons, any problems your kids might have, etc. Rely on the director to get the best available for your kids, and if they do not, let them know it. If they do, then really let them know how pleased you are. Be prepared to shell out some coin, but in the short and long run it will be well worth it.
NOW...WHERE TO GO!?!
I recommend Wintergreen which is about 2.5-3 hours away and has a separate and well known childrens ski school. One stop shopping...equipment, lessons, lift ticket all in one place.
A beautiful setting with a great snow adventure park (Ridgelys) where the kids can play (WAIT...it is not open mid-week)...have tubing hill, pool, good restaurants, etc.
Secondly, I recommend Snowshoe despite the driving distance.
Third...well perhaps Seven Springs with an excellent school, and a myriad of things for kids to do when not skiing (if you stay there, and I recommend you do if going to Seven Springs), and others...Liberty, Camelback, and Jack Frost in PA.
If you want to hear more of my experiences (I started all my kids at 3-4 years of age) and my experiences with my grandkids, send me an PM with your phone number and I will be glad to give you a call.
AGAIN...for the young never evers...let it be FUN for them. By the way, the 7 year old should start off learning to ski before trying snowboarding (should this subject come up).
ENJOY and take care,
The Colonel
