Just thought I would share a little tip that allowed us a great vacation.  Derrick and I put all of our monthly expenses on a credit card which gives a point per dollar.  We pay the card off at the end of each month, meanwhile accumulating points every month. 
The vacation that we just took was paid for with our points.  We got a 5 night stay at a participating hotel and bought our attraction tickets with our points as well.
I don't recommend this for anyone that has a hard time with discipline of a credit card!  Only do this if you spend only what you have and pay it off each month.
Otherwise, it's a great way to have a "free" vacation!  :)
