I also just booked flights, room and Club MoBay for Nov. We don't go into the lounge - too anxious to get outside and breathe! My wife may go in to use the washroom and change into appropriate clothing and I have our escort bring out a couple rum punches to go.
Twice out of 6 or 7 trips there were no lines at immigration or customs so we really didn't need it - still will not take that chance especially with the medical stops now.
