I had the same thought, but can't be sure either way. Still digging around to find out.
Over Fright Nights it closes at dusk in any case.
Rumba is an interesting one at the moment. It's been closed for an extended period of time, and that's sort of flown under the radar. Many of my recent visits it's just been sat there, although on Thursday it was testing, with staff in all Watcher positions. Saturday again it was dormant. Two weeks to get it back open.
Thorpe did say earlier in the year, on the Facebook passholder group, that it's a seasonal attraction. I guess it makes sense; it's a staff intensive attraction that is out the way and will have a low ridership in autumn. A different kettle of fish to, say, Tidal Wave, which though expensive to run and has low autumnal ridership, is very prominent. Too prominent to close.
Remember in 2020 when Rumba was 'transformed' for Oktoberfest into the Oompah Rapids? That feels a lifetime ago, and now it's closed for basically the whole event.
The park need to do something with it. Realistically, the park lack a mid-level water ride; one that gets you wet, but not too wet. Rumba and Storm Surge are rides on water, but barely get you wet.
Updating Rumba, with new boats and effects, could work. The other option would be the scrap it entirely and put a new ride there. With some work, they could create a closed water system there and put in a new water ride (new gen log flume with restraints?), but it won't be cheap.
The issue for Thorpe right now is they still have Slammer SBNO, next to the big new thing, they've got flat rides which are nearing 25 years old, they've got an elephant in Ghost Train, which surely can't operate as is until the end of the decade, and coasters seem to be the main draw to the park. Where in all that do they fit in a Rumba replacement?
So the bigger question is: do they drag our Rumba as much as possible, rolling the proverbial turd in a bit of glitter, or do they take the hit and SBNO-it, hiding it behind a few extra trees?
Neither is ideal, but it feels like we're leaning more towards the latter.
