Mexican Fiesta

(Rob, I'm not finding this info on the site -- maybe just not seeing the obvious?)
Anyone gone to one of the big, Mexican fiesta productions over in Ixtapa? (Barcelo?) Is it worth seeing or a rip-off? Approx cost? Any ideas for a better large-scale production?

EMBARC had a fairly low-key, but entertaining "Mexican Fiesta Night" at least once a week last season, (Tuesdays?) and I believe they do so this year as well. There was no extra charge, just have dinner down near the pool level at their reasonably-priced restaurant. We enjoyed it, had cochinita pibil.
