Well for starters, a large well lit and SECURE parking lot with room to maneuver trucks with trailers would be appreciated.
Well maintained trails that lead from the lodge to get to the hills would be huge.
Trailering from the Lodge to the hills takes away riding time and can be a hassle in an unfamiliar area. (Parking and re-parking)
A good restaurant (at the Lodge or within walking distance) with a sledder friendly atmosphere is important.
knowledge of a good shop nearby with top notch sled mechanics would be helpful should the unfortunate breakdown occur by one of your guests!
Inexpensive rooms, hot tub, continental breakfast (if no restaurant available).
A smiling, happy to serve the guests attitude is key. Too many places act like we're bothering them instead of being a welcome guest.
A web cam in your parking lot so us, over here on the left side can see the snow conditions and the amenities of the Lodge before we make the long drive around would get you a lot of business.
A small fleet of good rental sleds to make package deals for folks who are interested in sledding but not quite ready to pull the trigger on them would help.
(Check to see if there is already a rental fleet nearby and work a deal with them.)
A website that shows you cater to the sledding community could gain you a lot of business
Stock the lobby with trail maps of the area and a white board with the latest grooming reports.
Invite my Wife and I over for a weekend "On the house" and I'll give you the rest of my consultation services for free!
Good luck and best wishes for a successful endeavor.
