Martha - no peso&#39;s&#33; We use the Almighty ??? maybe not... Dollar  <img src="http://www.cruisecrazies.com/community/images/forum/tr-emoticons/laugh.gif" style="vertical-align:middle" emoid=":laugh:" border="0" alt="laugh.gif" />  Anyhow every one in Mexico takes dollars, so it&#39;s much easier, just try not to get change.
