Congrats on the cruise ship job! How many passengers on the ship? I worked on one that went up and down the mississippi river and held 420ish guests. We worked 12hours on 12 off for 6 weeks,no days off, no where to run on that small ship. 6 weeks on then 6 to 14 days off. My advice, make friends in other departments quickly and hang out with them. You'll see enough of the galley staff while you are on duty.
Hiding out will be a bit easier with the entertainers or housekeepers. Plus you will have different backgrounds and experiences to share.
To answer your question, Apply to work at a stadium. They would probably love to have someone of your cruise ship experience when you are finished. Try to start making contact middle to end of july. Be honest and upfront with them, there is plenty of work to go around,they are always looking for part-time workers. Take what you can get to get your foot in the door. If you are good at your job they will quickly figure that out and move you somewhere better suited for your abilities. Major Race tracks are good for one weekend of working your ass off which you might be tired of doing by the time your ship experience is finished. Start thinking about where you want to live now and watch for craiglist ads in that local market. You never know when your job aboard the cruise ship is going south (figuratively) because they just had to fire a bunch of people and now everybody else has to pick up the slack or whatever else may happen.
You may make friends with people aboard the ship and all want to live together and hang out off the ship. Be open to whatever oppotunity life presents you with.
Maybe you want to see more cool scenery and work in a national park? Do you already have your passport, Maybe you want to spend your winter months on a us virgin island. Your already packed up and living out of a suitcase, put your toes in the sand for thanksgiving and xmas holidays. You may be away from your family but it may be worth a shot to try it once during your life. Keep in touch and let us know what you decide. Cheers!
