The FAQ that I spent time putting together for this forum has actual temperatures on that page that are reflective of what temperatures have been all week!
Just curious - where did you get the idea that you would have to pay extra for a fast boat from town or someone other than the onsite op (which to my knowledge DOES charge more for the fast boat option)? That's not the case for most operations. Avoiding long boat rides is negated when you are on the large slow boats - which is what DP runs unless you upgrade to a small fast boat. The average boat ride from mid-town hotels to Palancar for example, is 25 - 30 minutes on a fast boat. The boat ride from Sabor to Palancar on a large DP boat is 20 - 25 minutes - Just providing this as an FYI - it seems you may have been given some inaccurate information
As far as experiences people have had at Sabor - there are MANY threads covering that topic here and of course places like Trip Advisor. This forum has a great search feature at the top of the page. Search Sabor Cozumel and you'll get a large range of opinions on that hotel.
Mossman just stayed there a week ago - so search his posts and you can read about his experiences
