We were group of 12 people, started the tour nice, arrived at Sagres around 1:07 PM after 3 hours boat ride, the guide informed us that we have 1 hour to look around and at the same time the guid said they will leave at 2:00 PM. At 2:00 PM everyone boarded the boat except one couple where they were stuck at a store dealing with slow owner writing a manual receipt. At 2:06 PM the guid gave the order to the captain to abandon the couple and leave, thanks to the rest of the couple that insisted for the boat to wait for them. The guid at this point insulted all of us Americans and said "I'm sure you don't do that in your own country", but the guid forgot that the cause of the delay is their own country people, and forgot that the couple were spending money for Portugal. The comment was not not appreciated despite the fact each person paid €60 just to be insulted. The actual staff of the boat were beyond great and awesome. The tour is ok, but I would recommend do the same activities on your own. Nothing really in the town to see except wasting 3 hours of your vacation time.
Remember, if you decided to do that tour, do not be late or better yet don't leave the boat.
