Dress Code at Mayan Palace NV

What type of dress code do they have at the Mayan Palace at Nuevo Vallarta? Can we go casual or is it dresses, slacks, chino shorts?

The dress is as you wish, keeping in mind that it is a family hotel/timeshare. They have a casual dining room at the far end of the pool. They have a table cloth and candle lit restaurant next to the pool. While we were there, we dressed mostly in shirts and shorts, if we went to a fiesta or a special dinner, I wore Dockers,a print shirt and Tevas.

I would suggest a t-shirt with large letters on it that say NO TIMESHARE.
