I love it when you say-

No chance to make a choice: This is one of the disadvantages of group travel, you are limited in your choice-making. If, for example, you want to travel on a particular route and everyone says no, it has to be route B, you have no choice but to accept and move along.

That's my hitch that I can't be driven on others; mercy. When I go out to see a place or stay somewhere it has got to be on my terms, my wife is exceptional because I can't overrule her.
