We toured New England a few years ago, with Tauck and had an excellent experience with this company. The hotel properties were high end and the dining selections were first rate. There is also quite a substantial amount of "time on your own," which we really liked, too.
The only negative for us - and this is not a Tauck issue - was the packing and unpacking.
We would tour again with Tauck in a minute and may plan to do so when we are ready to visit Australia and New Zealand and Great Britain, both of which we would prefer to see via land tours.
We received a Tauck brochure yesterday, and several of their tours now include cruise and land tours, which is a real plus for those who like to cruise, as well as take a land tour. A very good option.
