We had good friends we did short trips with & did not really work but we tried again
Went with these long time friends to an AI for 2 wks & vowed never again
we then did a river cruise with the same couple & after that it is NEVER AGAIN
We just go on our own now & after being together decades (a long time) we know what works for us & what does not
I organize what we like & if others come along I tell them to do what they like & we can meet up for drinks or dinner
