Thanks to everyone for all the advice - posts here on this thread and PM's. Sorry I wasn't more engaging this past week, but year-end work deadlines and budgets kept me away.....
some of you asked me to be more specific, so I will now --- I'm in my 40's and "average" :) -- when it some to SP's, I don't need any extras, just a relaxing, stress-relieving GFE experience. I admit I like my SP's on the young side, but I know that too young can = unsatisfied..... after reading the reviews of EmmaA and LiliL a little older can = a fabulous experience --- I admit I wish one of them was in Ottawa during my visit.
Again - I appreciate all the advice so far. I'll be sure and post my experience after my return.
