We had an amazing time at the Venture Retreat Center! It's exactly what you might expect. We chose this house for an adult summer camp, so the vibe of the house was ideal with the bunk beds in every room, no frills, large open spaces for big gatherings, long dining table that could fit everyone together, large field for kicking a ball around... it was perfect! We weren't looking for anything fancy, we actually liked that this house felt like an old-school summer camp with eclectic little things here and there.
Only thing to be aware of is there's other guests houses on the property that can sometimes be full while you're staying. We rented the big house, and weren't aware that a yurt and cabin nearby had 2 different parties staying, so it wasn't completely private and we had to keep our music down. Other than that everything was great!
