Glad you had a great first cruise. Just for future reference, you can pack any kind of snacks in your luggage you like to keep in your cabin. Even though many ships do offer shops where you can buy goodies to keep in your cabin, you will find that buying them pre-cruise will be less expensive.

Thank you for posting your review.
We always bring a few shelf-stable items in our bags. Turkey jerky, peanut-butter pretzels, etc.
