Do you notice a big difference when there are 2 or more cruise ships in town and who gets best parking?

Perhaps it was due to the Thanksgving holiday, but there were a lot more cruise ships in all ports in November.  They seemed to have staggered arrival and departure times but the crowds were larger than usual. One thing I noticed was the number of shuttle buses right at the gang plank that took passengers down the dock - a life saver for the disabled for sure.  Odd part was that most people did not notice them and began walking.
