We did the Las Hadas resort tour through Carnival. It was about a half hour bus ride there, about four hours at the resort, and about a half hour ride back.
During the four hours at the resort, there was a lunch buffet with some very nice food... a wide variety. Also, and here's why it's $85, the entire time there was an open bar. In other words, free unlimited alcoholic drinks (or soft drinks) during the entire time you are there. I'm not just talking about beer, either. There were several bars at the resort, and you could order anything you want as many times as you want from any of the bars. Needless to say, some of the 20-something males on this tour thought it was THE GREATEST TOUR EVER! I really don't drink that much, so it was no big deal to me... but I did enjoy the lunch buffet.
By the way, this was at the Karmina Palace Resort at Las Hadas. Personally, the reason I chose this particular tour was I saw in the photos that this resort had a whole bunch of swimming pools. My fantasy was to spend the afternoon swimming in the pools and lounging around. Unfortunately, the water in the swimming pools was just too cold for my tastes... and even though they had multiple pools, not one of them was any warmer than the others. No jacuzzis, no hot tubs, nothing warm. The ocean water was significantly warmer than the pools. So, for me, this was not a place I would want to visit again. But some people might not mind the pool being that cool, and others would absolutely LOVE the unlimited free drinks... so, as they say, one man's junk is another man's treasure.
