Just got back from Cabo and had a blast. We did this tour that some American guys started called the After Hours Tour. It was amazing, there was no uncertainty on what to do, these guys took us to all the hot spots in town. Definitely worth it, these guys know how to party.
Marlin fishing is extremely popular in Cabo. Everyone has seen the pictures of the fisherman posing proudly by their catch. The Giggling Marlin Bar allows you to experience that same feeling. Except...they let the marlin catch you! Hoisting you up by padded ankle straps, they allow you to "hang" with the marlin proudly displaying you. Be aware that as you are hanging upside down, all the blood will rush to your head and they will then give you a shot of tequilia (or other shot of choice)!
The Finestra Hotel has a happy hour from 4-6 p.m. two drinks for the price of one. You can sit by one of their pools and watch the sun go down. The drinks were very good and the pool area wasn't that crowded.
It's a beautiful hotel and has a wonderful large beach area.
You can make friends easily in this bar. It's a cool place to stop by before heading off to one of the clubs. I just prefered to sit with my tequila and chat with whomever was there.
