Lots of great tips (sounds like you should skip the boot driers!).
All of the businesses of this type that I have seen succeed are those that become friends with their customers. That creates return business and referrals and a full house when others are sitting there wondering what they are doing wrong.
Good luck!

X2 John! This is now sounding a lot more like how do I succeed with snowmobilers than what amenities do snowmobilers want & need. Of course we want it all @ an attractive price if starting from scratch but now sounds like they are working within pararmeters of what is already available & spiffing it up would be my best guess without more specific info. Most of all we value snow & lots of it as nobody going out of their way for marginal snow conditions as we have all had that unfortunate or misrepresented trip sad to say.
