Destination Fitness

Hi all, I wanted to ask if any one has put a trip for their clients together? For instance a retreat. I was thinking that it would be great way to travel and plan a trip for clients to get away and workout. Offering outdoor fitness excursions, nutrition demo's and possibly fitness on the beach. How do I charge for that? Do I plan all the details and put a price in there with a charge for my services. Do I charge for putting the trip together and the personal training sessions and workshops? Do I put those seperate and if folks want to participate then they would sign up for what they want seperatly? Or should it be one package with one price?
