Just looking at the ABD website, and it looks like they have added a 6-night Golden Path to Yosemite trip. It goes San Fran to Yosemite to Tahoe. I haven't looked at it in detail, but it looks very similar to the 7-night Golden Path to Yosemite (just in the opposite direction). Looks like a decent price reduction though. The 6 night ABD is $2699 and the 7 night ABD is $3429. Haven't looked at the differences in detail, but the biggest differences seem to be one less day in Yosemite (and the associated activities) and some of the restaurants are different. Maybe this is a domestic version of a Gateway trip without actually calling it a Gateway trip.
I haven't decided whether we're going to add any extra days. I know we're not going to add a post night through Tauck in Monterrey because the price for the room was too high. I left my notes at work, but I think it was $300 per night. If we don't extend the trip, we'll fly roundtrip to SF too. I'm going to wait a month or two to decide on that. I was planning to avoid Orlando this summer, but DS really wants to go to Universal again. The last time we were there he wasn't tall enough to ride Dueling Dragons and Incredible Hulk, but now he is and of course there's Harry Potter's Wizarding World too. So, I have to decided if were going to Orlando or taking any other trips the summer before I make a decision to spend any more money or time on the Northern CA trip.
