you should start your marketing speech like that:

What are you guys willing to pay for such an package?
You might want to make sure you can get adequate insurance - especially since dope is legal.
If so, you might want to arrange some way to rinse wetsuits - if you can do it with warm water, perhaps from a solar camping type system, it might add irresistible convenience by allowing extra sessions without the discouragement offered by the prospect of trying to put on a cold , clammy wet suit besides keeping your camper cleaner.
