Thanks to you all for the replies. I'll gladly take a PADI instructor with me from here...but she'll have to be about 18 with a fabulous body and be willing to pay her way in various ways. She'll also need to be very discreet so my wife doesn't notice that she's there!!!!
Seriously, thanks for the advice so far, I guess my best option will be to complete over here but assuming the regulations there are so relaxed I could probably get some dives in anyway for some open water experience before I complete here, I'm visiting as part of a wedding party and another member of our group is an experienced diver so I've already got a buddy lined up!
