Holland America and Princess both offer cruises and land tours. Huge variety of itineraries.
My suggestions:
If you've got the time, do a land tour first (about a week, altho' many lengths are offered), then finish with the cruise. Some land options are "energetic," and the cruise will allow you to relax from your touring!
AAA had a big program the other day, and followed up with some deals.
They'd be an excellent choice here in TV.
Look into Alaska Airways. They offer non-stop Orlando-Seattle service, which gets the largest portion of the flight taken care of.
I could go on and on, but will spare everyone!
