Providers so i've read a lot on here and have also been told a few times, that when you contact them you should be ready to go THEN. Do you ever consider booking something in advance? What are the pros & cons for you? Asking because I have.a birthday in few weeks and I thought it would make my Bday more stress free if i was able to book someone in advance rather spend my entire birthday back & forth with fees and availability. Etc. I'm live in NYC and it'd probably be someone local. (not sure who yet.)\
