I agree the internet is your friend. I have had activities go south to. You learn from trial and error. You will also find that pulling together a group sometimes can be extremely difficult. There are times I can have 15+ people in a social and other times 4-5. That is ok. Tell the residents you need them to help you or that your administrator wants more resident participation. I have found that both of these situations help increase the participation level. Good luck and I hope this helps!
