ooo where to start! oasis lanz is ideal as it's right in the centre of town,costa is not as lively as pdc,more families and couples but there is a huge choice of bars and restaurants,try the light house,scots and wrye and papa jacks for live music,if the girls like kareoke try saxos right out of the hotel down the street then look up it's upstairs above jumbo chines restaurant,it gets busy later on in the evening 11/12 ish and i think the nightclubs coyotes and dreams will be open then,just opposite the main market square.
there is a market on friday evenings in pueblo marinero.go just opposite the hotel through the alleyway between the chinese chulin and gift shop,this takes you in to plaza tanderena,here you have papa jacks bar,live music,the jug and platter, lovely sunday roasts,scrum and tackle, rugby bar,the british cafe great brekkies and burgers,scots and wry,footie day time,live music at night,great atmosphere,then thro into the next square is the market,also bars shops and retaurants,orient express and hooks for cocktails,chispas for really cheap drinks,local bar! and el patio and a tex mex!,
dont think you'll be bored!
also the buses run to carmen and back all thro the night,every hour but check at the bus stop and you have to get off at the san antonio and walk along the avenida to the main strip ( centro atalantico) cos the road is one way now,no probs getting back it stops outside centro atlantico.
and rancho texas? def worth the night out,lots to eat and drink all included in the price but i would book it with the rep as the more that go together the better the night!
phew i'm exhausted now! hope it all helps tho.

Thank you for your reply I am sure we will have a great time, even better now we know of some places to go.
