Hi @jamesmahoney, happy to help with this.
Cool.
Sounds like you have a solution in mind, but if you’re not settled, and happen to be using Wordpress then I’d like to recommend something I’ve looked at in the past. A plugin called GeoDirectory. It allows users to add markers to a map, with various custom fields including images if available, but it also has built in review system, so other users can comment on places. Unfortunately it’s hard to fully appraise as the free version is too limited. Might be worth looking at?
