went for their 4 day formosa holidays 2 years ago. tour guide was professional and knowledgeable. talks 99% of the time on the bus so u can either listen to his history lectures or let them lull you to sleep. most of the makan is 1 or two round tables with tour group. sit with the ladies if u feel hungry.
also tried their 1 day hot spring tour up to the mountains. worth taking up as they provide much needed motor transport.
