I do not believe you have to pay to see the venue. There are people on site to answer questions. You may want to give a call first to make sure someone is there to answer initial questions. Looks like they are busy at times.
They have open houses every Wednesday night (I believe) and they have staff there waiting to give people tours. After the tour they do a sit down meeting with you and give you the breakdown of costs!
No you do not.
