> How much money do I need to give you to go on a decade long cruise ship ride?

Depending on the details[1], anywhere from $1M upwards.

[1] Is it all expenses or do I have to pay for food, etc.? Where is it going? Are there any stops for excursions and tours? etc.etc.

kinda low

Seriously. Embarrassing.

A hundred million dollars sounds good.

2 billion dollars. In cash.

Do you take the money with you on the cruise? I imagine fully packed rolling suitcases that occasionally shed bills at the seams.
