Need places to park RV while taking cruises--out of TX

I had a similar need with Las Vegas a month back- we were flying back to our hometown for 2 weeks. Ultimately, our options came down to 3 things:

1) Getting a campsite and just leaving the camper parked there (benefit: can leave camper plugged into electric; con: cost)
2) Finding a storage facility (benefit: cost; con: no electricity)
3) Parking it at the airport parking lot (benefit: convenience; con: cost, but still cheaper than a campground)

Your options will be similar- just change "airport" to "cruise terminal".

Stayed at Jamaica Beach RV Resort for a month back in 2012. The owners were so nice they drove us to the ship, and picked us up a week later on their way to/from church (Sunday to Sunday.) From cruise port to MH door. They kept an eye on our rig while we were gone also. :)

Don't know if Dora and her husband still will do that, but you might want to send them an e-mail and ask. Spending those other three weeks on Galveston Island was easy to do. Reason we spent a month was to keep the daily cost down and try to stay in budget. :R

Back south/west corner of park. They've gotten much bigger since 2012.

We rented a space at Jamaica Beach RV Resort for 2 weeks (about $400). Did a 7 day Caribbean cruise and parked TV at cruise ship port was about $115. We had no problems with theft. Need 30 ft of sewer hose in sites. We did store water hose in bay while cruising. BTW park is about 30 min drive from cruise ship terminal.

Just came back from a 21 day cruise. What we did since we are winter Texans and stay in Rockport we came down a month earlier than we usually do and setup the RV at our site and then drove back up to Galveston and stayed overnight at the Inn at the Waterpark for $109. This included Continental breakfast, free parking for the 21 days and free shuttle to and from the cruise terminal.
