This is not intended as criticism - but since you are jaded with travelling, maybe you should donate the money you would spend to someone who would get an absolute thrill out it?
I won't nominate myself...but, for example, many cities have a 'send a kid to camp' fund. You could give a lot of kids who never get out of the inner city a chance to enjoy a whole different world and open up lots of possibilities.
When you are bored with your life, it's time to give to others rather than looking to please yourself.
