We head back to Coeur d'Alene tomorrow and will be there until Tuesday. We were & will be in the King/Twin suite - same as you. It's an AWESOME suite. I think Coeur d'Alene has had the largest Worldmark suites we've stayed in to date - and we've stayed in quite a few. The suite here in Yellowstone is pretty big, but the master bathroom can't even come close to comparing with Coeur d'Alene. When we walked in, the kids ran in, saw the master bathroom and my oldest yelled "Mommy and Daddy have the biggest bathroom we've ever seen!" It was kind of funny - then I told them they had to use their own bathroom. They all whined a bit at that revelation. LOL!
Silverwood! I love Coeur d'Alene. If I ever move back to Idaho, it's to CDA or anywhere on lake Pend Oreille. I have lived in lots of places in the PNW, and N.Idaho is the most beautiful to me besides the redwood forests.
There is a water park at the Best Western. If you end up going to Silverwood look online because they offer discounts after 5pm. etc.
Look out for wolves!
