With the weather looking okay, the only chance I'd get to visit this year, and having heard that the first Saturday is quiet I headed to Chessington today. Had a great day and it was indeed very quiet! Longest we queued was 35 minutes for Vampire with most other rides being 10-20 minutes. Operations also seemed slightly better on some rides (still generally shocking compared to other parks but an improvement none the less). Didn't venture over to the Hotel side of the zoo so I have no idea how well that development is coming along. The only ride I witnessed break down was Rattlesnake, twice. Once when I was about to board everything just stopped, and second time when I was on the ride break run before the station so I sat there for 5 minutes. Other than that a great day and some photos taken:

The sky was very fitting for a Halloween event!

It was going so fast it's blurred.

In we go

We made it!

These poor people didn't. R.I.P

The count wishes you all a happy Halloween!
