Yes. Just remember to roll up the awning and secure anything that can blow around in a storm. People leave for short cruises all the time.
Yes, there are many people that do that here. Just reserve and pay for your site and there shouldn't be any problem. We are camping at jetty right now for the week and we've seen several campers that just sit here for 3-4 days at a time with nobody in them so we guess that they're going on cruises.. check with the main office and I'm willing to bet they might even have a shuttle that'll take you to the port. I know they have a shuttle for the victory casino boat.
As long you call and reserve your spot.
