We are spending 4 nights at the beginning of our trip in San Pedro and wonder what we should do here.

After this we are spending a week at DuPlooys in the jungle and visiting various caves and ruins, then going to Turneffe Flats Lodge for a week of fishing and snorkeling.

Is there something special we should do on AC that we won't find in the other places we are going? I appreciate any thoughts. Thanks!
