Congrats. If you do make it down again try to do it in June or July as those months tend to have the best bite by far. We’ve done ok in May, pretty good in August, and then mostly ok again September thru December. Had an epic trip a few Januarys ago but have never done well in Feb Mar or Apr.
As to Golfito, you didn’t miss any nightlife because there really isn’t any. Just hanging out at Banana Bay and Fish Hook marinas, or go to Casa Roland which is a really nice hotel and completely out of place in Golfito.
