Saturday afternoons in February are definitely busy. Check www.flightstats.com. Today (Saturday) there were ten flights arriving between 2:00 and 2:30 and late February will likely be similar.

We are arriving Saturday, February 21 and are using Club MoBay. We used it last year in April and it was a great way to start our vacation. We waited in the lounge about half an hour until our driver arrived, so I think you should be fine waiting there for the rest of your party. We had a couple of rum punches, and the lounge attendants were quick to supply a refill and even one for the road.
