Here's an idea ...
Get a part time job, in addition to your current full time job, and put all the money you earn from the part time job into a savings account. When you've got enough money in that account for a tour ... go and enjoy!!
I know several people who do that in order to go somewhere hot and sunny for a few weeks in the middle of winter. They pick up part time Christmas work, and then hit the beach on an island somewhere in January.
