It varies a little bit but not that much--you get your meeting time in the email but is usually somewhere between 8:30-9:30am. Mostly just depends how many people are at Grand Flo vs nearby resorts as that determines the number and sequence of stops they make. We've had times were there were dozens of people boarding at GF and times where there were only one or two families, times where we headed straight to the port, times where we just stopped once at Poly, and times where we stopped at 3-4 hotels. The more stops after yours, the earlier the bus will pick up. They target for everyone to arrive to the port between 10:30-11:30.
