Hi what is the weight capacity. And for a group of people do you have to make reservation.

300lbs however they'll take everyone's weight at check in and make note of anyone weighing 260-300lbs. Essentially they just make sure to up the wind in the tunnel to accommodate

You need to make reservations either way, weight limit I think is 260lbs

Wind Speed can be turned up for each individuals weight. Reservations are not required, but for a group it might help speed the process of preparation to accommodate a group.
