Mark,
Welcome to the business of performing at Senior Venues. I have had the very same experience with many of the places over the last 15 years. It does get tiring and I have often thought about simply not returning to them. Several times I have contacted the manager and explained the frustration of not getting return phone calls - it didn't help. Just today I got a call from a very special AD friend of mine almost in tears because she had to cancel my years bookings due to a budget cut! The business has changed over the last 5 years. Many of the places have been bought out by corps that have no idea how to provide services for the residents. I often see people move from one place to another because prices increased but services did not. One place I lost has decided to do NO entertainment for the residents - they replaced it with physical activities. Go figure. Anyway, hang in there. As many have said there are a lot of the Independent living places everywhere now.
