I'd give it a 4.5 if I could, because my only issue is the same as the other reviewer--it's very easy to miss the entrance. The signage is tiny and then once you turn into the correct area there aren't any additional signs to point you in the direction of the correct building. I had to drive slowly all the way around, creeper style, trying to read the names of the business on the doors. Otherwise the experience was great. The staff were efficient and friendly, enforcing the rules without being scary. The room temperature was warmer than I expected. I'm usually freezing in every building I enter during the summer, but maybe because it was a rainier, cool day the AC wasn't as high. I was comfortable in a short-sleeved t-shirt topped with a long-sleeve (and again, I usually freeze). If it had been easier to find it would be an easy five stars.
