I used Epic Los Cabos for my group trip in June 2010.

We scheduled private transfers to pick up my group at the airport.  When we came out of the terminal the epic driver was waiting for us with other employees to take out bags.  As soon as we got to the van, we were offered waters, sodas, and cervezas!

They were really great.  When they dropped us off at the resort they told us to call if we needed ANYTHING.

We price shopped for a group trip to ATV or deep sea fishing and their prices were the lowest.

They took my group out to ATV and the whole group said it was the best time they have had ATVing (and they do it every year) and also that the driver and staff were so polite!

I would def. recommend!!
