Map shows routing accurately, but some tees 8-16 were hard for me to find. And the map is very faint when reading in the sun on your smartphone. I recommend printing it.
Estero map is now updated. I played a year ago for the first time and they had re-routed some of the course and it was very frustrating.
Estero is a better course, but only a 2.75 in my book (an average course....if I'm being generous) and Bonita Springs is about a 2.0 (below average)....but the throws required still make it fun. DG in SW FL is weak. Sarasota has some good courses if you have time to drive a couple hours north.
