If you are in Delaware...there are quite a few AMPs around here. There are the bunch in Elkton, MD and then some near Wilmington. The thread about the list of Elkton MPs has ones for Delaware, PA, and NJ that are in close proximity.
I suggest Trolley in Wilmington. All the AMPs I go to don't require appointments. Some of them don't keep track of them anyway. I recall going into an AMP normally (without an appointment) and 5min later came another guy who had called ahead. There weren't enough girls so he had to go elsewhere.
But Trolley is great. Great massage and great finish (hj only for me so far). Just go with the flow. You shouldn't have to push them to get to the good stuff...but if they are feeling cautious, then they may not do anything with you. In those situations...roaming may help. But roaming leads them to believe you want FS (and they cut the massage time short). If they brush their breats on you...it is a good sign.
