On my day off from Disneyland, it suddenly occured to me that I could use my pass and rental car to get into Knott's, check out the Haunt store, and get some chicken to go. It took longer than expected to get in because I forgot that parking at Knott's is always confusing. They were having us park in the waterpark lot, but had blocked off the entrance from the main Knott's road, with a sign to turn left at the end, but no sign indicating that you needed to take a second left onto Beach Blvd to get into the lot. If I didn't know that Knott's has been inept at communicating which parking lot to go to and how to get there for as long as I've been going, I'd say it was a cynical attempt to get people to spring for the paid parking lot that they have to pass first. If that was their intent, it failed, because most people stopping at the premium lot were clearly stopping for directions to the regular lot.
It was so easy to get chicken to go, and a fair amount cheaper than actually eating in the restaurant (and even though you get less food than you would eating in house, you still get quite a lot of it). Not really any seating options, but because nobody was at Knott's today I was able to get a table by the park exit.
The Haunt store is in the old Emporium and is really, really cool. It's akin to the themed Haunt shops Universal Orlando does for HHN. If Haunt is going on during store operating hours, you need a Haunt ticket to visit it, but if Haunt isn't happening or it's before 4 PM or so, anyone can enter it from the marketplace.
In case anyone is like me and was looking for the 50th Haunt book, my big tip is to enter the park. It was sold out of all the gift shops in the marketplace; then the first store I walked into within the park had a giant display with several copies available.
In contrast to Disneyland bursting at the seems for the last three days, Knott's was completely dead on a Tuesday. Definitely helped that there's no Haunt today. It was so dead that GhostRider was a walk-on, and while I was eating my chicken I saw it cycle with many empty seats several times.
@mickEblu if you're looking to make your Knott's redemption visit, weekdays right now are a good time to go, and if you're off Tuesday, that's my top recommendation. Entertainment is nonexistent, but almost all of the rides are open and since Tuesday neither borders a weekend nor has a Haunt later in the day, no one is there (for what it's worth, there are also some restaurants in the marketplace that are also closed on Monday but no other day, so perhaps Monday isn't as different from Tuesday as I might be imagining). If you wait until Thursday, they have Spooky Farm running with some entertainment and things for the kids.
