Excellent, congrats, I know how good a feeling it is when your kids are living up to you expectations.
As a side note we followed the same methodolgy and Fozzy was the exact same way. He makes me so proud. He can find a door anywhere and let you know it's time. (Hotel, Timeshare, Condo, In-Laws, Friends, anywhere!
And actually we started the weekend after we got Fozzy. Saturday / Sunday / Monday (took off), and by Tuesday he was doing good. The two weeks following were "come home on lunch breaks" but after that he was good for 8 + hrs in his crate.
