¿Dondé está la cantina? (Where is the bar) Dos cervezas por favor (Two beers please) Besame (Kiss me) That's about all you need. The rest works itself out.
On a side note - sooooooo much english in Cancun that you don't really need spanish unless your searching for something specific and/or just want to speak spanish. I went on an obscene search for chispitas last year (sprinkles)
It may speak to what my visits down there haVe been that i can pronounce the first two without an accent, but need help with the pronunciation of the third.
Beh-sa-meh.. should do the trick... some others... dos tequilas por favor (please). 2nd word pronounce fah-vore. muchas gracias (many thanks) yo amo tu (I love you) and .... o mi dios, que bueno tatas. (OMG, nice shoes!)
