Booking App Schedule Cowlendar

TL;DR: If you can afford the paid plan, this is the service to go with.
I just downloaded the app and had a great experience with customer service when I couldn't figure something out. I haven't had much of a chance to use it yet. I am concerned about the lack of ability to block off dates with the free plan. I can't afford to pay for the app and I think this might be a deal breaker for me. I would return if I had the funds to pay for the services though.
