Steve - I love the sea days as well but when you get off the ship there is all that SHOPPING! And I love shopping!!!!!
If we aren't on an excursion we just get up and eat then go ashore and wander and come back to the ship and eat then wander some more then come back and eat again. With all that food it's no wonder we have to wander
On most ships the spa offers great deals on port days - that's a great way to pass some time and be treated like a king!
The very best thing about cruising is you can do everything, something or nothing - it's up to you. There are no rules. Enjoy!
