Interactive retreat

Hi everyone, I am new to this site. My husband and I have bought a year ago, this big house , with 11 bedrooms and an attached bungalow,where we live in. Our daughter and granddaughter were going to operate the big house as a B&B, but it is not working out, (work is a dirty word for this teenager.) I am overweight myself, need to exercise, diet etc. but I know how hard it is going it alone, so that's why I thought I will invite a small group of people and try it together, for 2 nights or a week My plan was: to have the group plan the meals and prepare them together, practice Tai Chi, and dance to lively music. Climbing the stairs to the bedrooms is a great way to add more exercise. Group support build in !!! I looked up some health spa's, but those prices are too high for my blood, so we can do it more affordable. Anyone think this could work?
