I do the same thing...charge almost everything that can be charged, and then pay it at the end of the month. It makes for a much cleaner checkbook, with one check going to the credit card rather than 100 entries for every little purchase, not to mention that it is gradually saving up for a future trip.
I can't remember the exact total of points on my last statement, but it was around 120 I think. But that statement was printed a day or two before I paid our April trip in full. So there will be 41 points on our next statement just for that, in addition to another 10 or so for the month's normal charges. So we should be around 190 or so in a couple weeks when we get our next statement. And that's when I was booked at CBR, and I have since upgraded to the Wilderness Lodge under this new discount, so it is only costing me an extra $506. So I'll get another 5 points for this current trip.
Since we try to go every year, I'm hoping to accumulate my points until 2013 (they start expiring in 2015), when my wife hopes to stay at the Grand Floridian for our 10 year anniversary. Hopefully, by charging our 2012 and 2013 trips, in addition to all our regular spending for the next 2 years, we can have $500 or more in rewards points by April 2013 when we go to the Grand Floridian. $500 bucks to put towards the tickets, dining, etc, since I can't imagine we would spend $500 on Disney souveniers!
