by NA, i assume you mean North america, So....
there are 4 different types of camps available here
1. Mt Hood
the camps there consist of MHSSC and Windells
MHSSC: smaller, cheaper, more barebones- I went there this summer and had an amazing time, very chill environment, really cool people run it, you will learn SO much.
Windells: Bigger, more expensive, flashier- you will also have a great time if you go here, but from different ways. At windells, it is more about hanging out with the pros and getting free stuff and shredding, instead of actually learning stuff (also guard yourself well here, the kids here have a habit of grabbing anything that isnt tied down...
the camps here consist of Camp of Champions and Momentum
Both are very large and flashy, like Windells, but perhaps even more...
Many pros also hang out here and coach, I Don't have personal expirience with either of them so i don't know how the coaching works and stuff
3. Woodward (Copper/Tahoe)
these are both fairly upscale and nice facilities. The main difference between these and the camps at hood or whistler is that the snow is not actually natural. If there was no snowmaking and grooming, it would not exist. because of this, the parks are smaller and do not stay open as long. Because of this, the focus a lot on their indoor facilities, so trampolines and skate parks and foam pits. I don't believe that there are pros that coach, but some visit.
4. snowless camps (Ohio dreams, whaleback, among others)
these camps can range from very fancy, to very basic and from quite pricey to affordable. remeber that you get what you pay for and do research on your own.
