Toadies only runs three cars these days
The way Chessington is going though, it'll just be a few hotels, a zoo and a few puppet shows with the way things are going.
Toadies only runs three cars these days. Judging it takes 3 minutes to complete the circuit, add two minutes for loading/unloading, you're looking at about a maximum of 12 people every 5 minutes. When you times that by 6 the potential result is the ride takes around 144 people per hour [PPH]. That is a terrible throughput for a ride at Chessington [let alone other parks] and knowing the park it's probably even less. This means if there's only a dozen parents with a couple of kids queuing, youre already looking at a good 15 minutes or more queue time.
Real investment needed in the park would be:
redeveloping the leftside of Wild Asia and putting a dark ride where the play house and maybe other rides are,
Ripping out Toadies for a thrilling fun family coaster [Juvelin, smaller Taron]
starting from scratch on a new dark ride for Tomb Blaster [like Ratatouille or Gringotts]
