We are looking for one more couple to join our Red October tour in St. Petersburg. If you are interested, e-mail us for more info. We aren't a group of four, but rather two couples who met on-line. All four of us are late middle age, the guys are both 61, but we aren't telling. We are politically liberal, and I don't know about the other couple yet.
We can e-mail our itinerary if you are interested. With all the extras including a tip, I think it comes to a little more than 800/couple for two days (two lunches in that price).
