They still do, and always have as long as I can remember. I haven't been on it in years but the website still says it's a free for passholders and a "nominal fee" for non-passholders.
Look I don't like an upcharge but this really isn't that big of a deal to me. If anything it's just another thing to incentive you to buy a pass which seems to be a big part of their business. I'm just glad the ride is open again, if it takes $5.00 to keep it open then fine. Also if I remember correctly the line for this thing used to be awful due to it's massive popularity and somewhat lower capacity, so if it takes $5.00 for them to make a little money on the thing and keep the waits down a little I'm all for it. If people are going to complain about anything complain about $40.00 to park instead of $5.00 to go on a really cool vintage skyride attraction.
