went about 2 years ago and stayed in the same area. I did a charter with Capt. Ricks out of Puerto Adventuras, cool little village they have down there about 45 min south of where you will be staying. Trolled with hoos and had an ok day.

They had guys running 2 Panga boats out of the resort, small little boats, that run right off the beach. You will get soaked immediately but they are fun. We trolled hoos as well and got some big mahi right off the beach. Paid the guy a little extra and he anchored up on a reef for us and let us snorkel after the fishing ended. Had fresh mango's waiting for us when we got back on the boat.
Two totally different experiences but both fun.
Enjoy!
