? Cozumel and Allegro

Want to find a good all-inclusive in Cozumel.  We went there once,
stayed at Presidente (1992).  Have heard good things about Occidental
Allegro.  Two adults, mid-50s, want good food, drinks, decent room and
snorkeling.  Also quiet place to read books.

Thanks for any ideas or suggestions.
