So, here's the set-up...
You have a crystal ball that tells you that you will never be able to travel again. This is the last year you will ever, for the rest of your life, have the opportunity to go on any kind of vacation.
You have four weeks of vacation time to use within the next 365 days. You have two choices and only two choices.
You can take all four weeks all at once, get on an airplane to a single destination, and 30 days later get back on an airplane to return home...never to travel again.
You can take four separate vacations of one week each. You will fly to your destination airport and return home from the same airport. These four weeks must not be consecutive. And, you can't go to the same place more than once.
What do you choose?
