I'd like to take a cruise with my immediate family, mother, 2 sisters and brother - all adults (26-60 yo). Me and my mother are often the only ones paying for stuff, so I want it to be not crazy expensive. I'd be cool with us paying for the cabin, and then extra stuff they can pay for. I'm thinking 4-5 days (we're in the Midwest, so would likely have to fly to our embarkation location). Also, only 3 of us currently have passports, although if we needed them, I would push the other two. I'd love some ideas.
Please let me know if I've missed any important details that would help identify.
Thanks for the assistance!
