If you're going to expect GFE and no clock watching, then you better book a longer session. One hour is way too short. For her to get in a girlfriend mood, you should dress the part, smell good, bring flowers, take her out for a nice dinner, make good conversation and shower her with niceties. In other words, give her a BFE. Book at least six hours... Expect to shell out at least $500 or more...
After all, you should make her real BF feel good about her being away so long!
