I did this ride long ago, when the course was different... so the only word of advice I can offer is that the ride back along the river will likely be quite windy.

Oh and if you don't want to camp - we waited until waaaaay to late to find a hotel last weekend (I was at a race in Wenatchee this past weekend), but found a rather quirky little motel on the outskirts of town called the Moonlight Motor Court. It's just been totally redone and reopened. It is kitschy (we had the Marilyn Monroe room...)relatively inexpensive and very clean. The only disappointment was that the magic fingers machine didn't work
