Wild Apricot is More Customizable/Flexible Than You Think
I work with a lot of clients using both WordPress and Wild Apricot together. When asked why they are using two separate systems, I usually get the same response: WordPress offers better customization options.
The truth however, is that while it's possible to simply purchase a WordPress theme and install it, if you find a experienced developer they can customize your Wild Apricot site to match most WordPress themes. This would save you having to work with and pay for two different platforms.
