Otherworldly Being

[Moonface]

I'm gonna guess you still didn't try Astro's Playroom yet? 

Also I'm curious about this one but not sure you'd know; does our primary school still do that bouncy castle day? I figured since you live so close you might have some awareness of if that still happens. XD

You guess correctly. Forgot that existed again...probably will do again. I blank everything but Genshin and Prime Video on my PS5...PS Store if it gets lucky too at the moment.  I should try Astro's Playroom at some point...

You should, especially since it isn't long to beat even if you decide to 100% it. Going by my trophy list, I earned the first at 12:58pm and the last at 5:14pm the same day, so it takes only four hours and that was going for the Platinum; if you just wanted to go through the levels and not go for every collectible and trophy it takes about 2-3 hours. I can't rely on my trophy list to tell me for that because I don't know if I spent time going for 100% in an area before moving to the next which would obviously increase the time between the area trophies. Regardless you can see it won't take much time at all to give it a whirl.

Also if that particular fun day happens still, forgot what they call it, I haven't paid attention or at least haven't noticed it the last few years. Possibly because I coincidentally have my headphones in use on that day. I know I did hear it a good number of years after we finished there, can't recall the last year I did. Perhaps I'll notice it this summer. 
I know one thing that happens at one of our old schools now, at WDF they seem to finish way before 3:30PM now like we used to, 3PM quite possibly as I tend to see them enter our store around then if I'm still working like on a Monday, or walk past my home sometime after 3:10PM.

If you get aware that they still hold that day you should see if you can spot any of the classics we had in our time are still in use or not. Although the only one I'd care to still see is the tube maze because that was GOAT.
As for WDF's finishing times, I know my mum told me they adjusted how the schedule works over there now; I think they switch up the end time multiple days of the week to stop kids from clock watching for the the end of the day or something. I do know lunch times got staggered to try and keep line times down on canteen food.

On the subject of places to go, I know you probably went to Chessington through your class winning sponsor day at Willie D*, but have you ever gone to any of the other big theme parks in the UK such as Alton Towers or Thorpe Park? If not would you ever care to or not really?

*Anyone wondering this, it's the short-hand name of the secondary school EL and I went to.

Legoland definitely been to, maybe Alton Towers...or I'm mistaking that as the Chessington trip. I usually end up with next to no recollection of theme parks because they don't leave a lasting impression on me or my only memory is looking at a ride and either not wanting to go on it or being very reluctant to, which may end up being 90% of them.  I look at images of rides and don't recognise any of them. Did go to Blackgang Chine in Isle of Wight, likely each time I've been to the little island....nah, and that isn't because of my dislike of rides but it looked...old. OK, shite, would not take kids there. 
If it's with the right people I'd go but yeah, I'm not a thrill-seeker so may just be there to watch others enjoy themselves. The only theme park I'd be very willing to go to is unfortunately not in the UK. It's obvious which one that is, being to do with the big N of course, or M whichever comes to mind first.

If you went to Alton I doubt you would have gone on a single ride since out of the three (Chessington, Thorpe and Alton are all under the same parent company) that one is geared to mostly thrill seekers and adult riders; I can't recall which way around it is for Chessington and Thorpe but one is tailored to all ages and the other to younger ages.
Never heard of Blackgang Chine before and that's also the first time I've heard of any specific thing to see/do at the Isle of Wight. Normally I just hear people say the location but never anything to do there. Looking at that park I agree with you it doesn't look all that; it comes off as a lower budget version of Adventure Island in Southend. XD

Not surprised you'd want to go to Super Nintendo World, and I doubt they'll ever have any high-thrill rides there that aren't suited to all ages until maybe way down the line when the park is big enough to start putting in restrictive rides. Whenever the Orlando one opens I'd say tack a few extra years on though because if it initially offers what the existing ones did for their openings that would mean there's only three attractions, and I don't think I'd even be willing to drive to Orlando for three rides let alone fly internationally for that. The park tickets would have to be stupidly cheap compared to the other choices for me to consider going, even if I did lose my shit over a Yoshi headband.
