We have had early morning CRT while at PO before and they do have buses running that early....it was also in Feb. I would ask the front desk what time they start running that morning and get to the stop a few minutes early. We typically get to the bus stop around 7 (I know this seems early!) but if you miss the first bus, it might be awhile before the next one comes. I am the type of person who would rather be early than late, but that is just me. I know some people take a taxi so they do not have to deal with the bus that early.
