I just returned from a fabulous trip to see various national parks and some of the most amazing sites ever in Oregon, Washington and California. Within a matter of days, we traveled to Mt. St. Helens(volcanic destruction meets rebirth), Mt. Hood (think skiing in summer in shorts), the Columbia River Gorge (holy waterfalls!), Crater Lake National Park (perhaps the most amazing site to behold), rode sand buggies on gigantic sand dunes, sand boarded (snow boarding on sand), rafted on rivers and hiked through the Giant Redwoods.
Now we also changed hotels a bunch of times during our journey, but any one of these sites would provide a fantastic non-disney vacation alternative. And if you could trade your points in, I know there are several RCI resorts out there (although we did not stay in any of them). World Mark has a bunch, I think.
Happy Planning!
