Imagine Sierra Club having a Club Med. Very rustic (not for people who hate camping) and for outdoor lovers but full of activities. You can hike with experienced naturalists, play sports (tennis, basketball, ping pong, soccer, baseball, ...) do a lot of arts and crafts (including tie dye), try archery, climbing trees, ropes courses, horseback riding, or just relax at the pool or the lake. Plenty of things to do in the evening as well. Good food prepared for you in the nice lodge and outdoor tables. And last but not least, super friendly and helpful staff!
