I worked on cruise ships for 3 years! If it's the "trapped" feeling, try the Allure or Oasis of the Seas with Royal Caribbean.
Allure of the Seas | Oasis Of The Seas It's a beast! You will NOT feel trapped on this monster.
What about Boston? Chad and I had our first date there, lol. We want to go back.
Savannah, GA is beautiful.
If we had a week off and didn't have to visit family in KY, we'd get in the car and drive the west coast. I like Portland and Seattle and haven't been in years.
