My wife and 3 kids (9, 9, 11) just got back from a 3 day weekend at Jay for some Spring snowboarding. All in all we all really loved our stay there. We had a very nice two bedroom ski in/out condo on the mtn ($299/night included all lift tickets).
We are all beginner snowboarders and found plenty of trails to keep us busy on the lower mountain. Condtions started out hard in the morning but due to the warmth and sunshine it quickly turned soft and to us was the next best thing next to powder (a little softer on the crahes)
We could not have ordered better weather for the weekend, freezing overnight, into the high 40's to 50's during the day. There is still plenty of coverage on the mountain with very few trail closings, none that affected us.
About the only downside to the resort, to us, was the price of food anywhere on the mountain. As a captive resident, meaning there is really no place else to go to get food, other than a local gas station/supermarket at the base of the mountain which had a nice variety at very reasonable prices, we were forced to pay for the $6+ cans of beer and equally priced hot dogs and hamburgers. To feed a family of five a lunch of back yard bar b cue food it cost us $54, not including beverages.
We also wish the lifts would have stayed open past 4:00pm as it does not even start to get dark till close to 7:00pm...thank you daylight savings time.
The staff was extremely friendly as were all of the guests who we encountered all weekend.
Sitting on the back deck, getting a suntan after a morning of boarding, munching on a burger, taking in the sights and drinking some beer made for a verry nice break.
I highly recommend this place but if cost is a concern, get one of the condos and simply do some grocery shopping before heading to the mtn. Easy enough to stop in, prepare some food, hit the restroom, grab some beers and head back out (for $20 instead of $60) and you are ready to go again!!
