I'm stealing a topic of discussion from the Rick Steves forum that was titled tourist traps. Not really the best title, but the spirit was what have been sites you've been to that have been a bit of a meh experience and also which ones were unexpected surprises. Lets keep it to actual Tauck tours we've taken. Also, NO dissing someone else's choices.
Here's a couple from our very first Tauck tour - the French Waterways river cruise (now mostly been re-titled Savoring France).
I was really looking forward to our visit to Pont du Garde and dinner there. I love roman history and was especially excited when the TDs told us we'd be able to walk on it. Arrived to find out a concert was taking place there. Our 3 buses of Tauckers arrived and the TDs had to shoe horn us past the crowds waiting to get into the concert. Got alot of angry looks from the crowd as they thought we were cutting the line. Finally got in and found we couldn't go on the bridge or near it as people were coming from the other side to the concert. Then we sat down to dinner at this lovely outdoor restaurant. The only entree offered was roast lamb which I detest. Thank god for good wine.
On the other hand, the last day of the tour we had a fun time at the Sophy Pic cooking school - wine tasting at 9am followed by a cooking lesson. This was followed by a stop at the Valhrona chocolate store where you could have unlimited taste testing of the huge selection of chocolate. If death by chocolate was possible it could happen there.
