Idea where to travel for honeymoon?

Do you want to go to Canada or just to B.C. -- it seems from your question it is the latter because driving to Alberta and beyond might strain the budget and driving time. But you already have in Washington State a beautiful seacoast and the breathtaking Cascades. But a few suggestions:

Victoria is a beautiful little city with nothing quite comparable to it in Washington State (or elsewhere in North America, for that matter). Vancouver is vibrant and thriving and can be compared in certain ways with Seattle (Vancouver's Gastown district and Seattle's Pioneer Square are practically interchangable) but is distinctive by cultural effects of its much greater Asian communities (south Asian as well as oriental Asian) as well as its libertarianism (it is almost impossible to get to Vancouver's downtown peninsula without traveling though at least part of its notorious near east side). The long finger lakes regions in B.C.'s Rocky Mountain valleys (Okanagan, Kootenay and Duncan) have nothing comparable in Washington State.

If you do choose to honeymoon in B.C. by all means enjoy the wines! B.C.s white wines are generally better than Washington's (some - such as Okanagan pinot gris - are among the best in the world); B.C's red wines are often not quite as good as Washington's best but many come close.

The Grand Canyon...

I went there with my husband on our honeymoon. We stayed in Kingman Arizona on historic Route 66, in a boutique hotel (the Brunswick). Then we went to the Grand Canyon the next day. We went to the west rim where they have just finished building the sky bridge on the Hualapai Reservation but you could also go to the North or South Rim. But the west rim is just as nice, maybe not so big.

Also the west rim is within driving distance to Las Vegas (where we got married). There is a lot to do in and around that area, aside from gambling. Best of luck and congratulations.

Take the Alaska Marine Highway Ferry and/or BC ferry.

It's like a less expensive less snooty cruise. You can take your car (If you like). You can get off at any port (and stay at a quaint B&B) then pick up the next ferry passing through. You can get a little birth with bed and washroom. You don't need a passport when travelling by land or sea. The scenery and wildlife are amazing. There are park rangers on board who give interesting lectures throughout the journey. You can design your own trip. You can get to little towns that the big cruise ships can't get to.

Venice and Rome is a nice place to go on a honeymoon. So is Cancun, Mexico

Vancouver's nice. It's been a while since I was there, so I'm not sure on hotels. If there's a Hilton or similar, at least you'd be familiar with the level of comfort to expect.

Banff and Lake Louise

...how about riding the Canadien Railway?

We have a cruise to Mexico for 6 days only 69 dollars and more to come.
