I went a few weeks ago with a friend, hoping to do Valhalla a whole bunch of times. Watching from upstairs in Lokis for the ride opening, we must have gone over to the ride around 1:30. Managed to get a rare free parking space earlier right opposite Travelodge, where just the other side of the wall people had paid £18 to park. Great opportunity to have change of clothes & shoes handy without having to pay for a locker. So, swimming trunks, old shoes, old jacket with busted main zip on, with 2 phones double bagged in side pocket, we boarded the first vessel. "When fear leads the way, the destination is never glorious" we are told upon entering the building. Sadly a fair few effects were off all afternoon - no red mist coming down on first lift hill, no hammers, no rolling log, and the explosions & fire at the very end were sporadic. I love the exploding boat effect on the left before the boat goes back outside, but it went off I'd say one in every three rides. Fortunately the water vortex & ring of fire were on all the time. We soon realised on the final drop, if you raise your hands, you can actually feel the warmth of the fire on your fingertips. I love the fire & skeleton display on the left on the final drop runoff. It looks fantastic.
We had a target of 10 rides, but when we hit that, we were enjoying it so much, and CBA going to get changed to do other rides, that we stayed on. We then went for the ambitious (though unrealistic due to time) target of 20. We were very lucky, it was the perfect storm of the ride actually working all afternoon, there being nice warm weather, and non-existent to very short queues each time. After the first handful of rides, my paper ticket had utterly disintegrated in my coat pocket, from this point onwards the staff just scanned me in. We had a good mix of seats. Front row was hilarious for the water that pours all over your feet from the left after both lift hills, and from the right just before both main drops. That's always happened on the front left, but I don't really recall it from the right before the drops, so I don't know if that's got worse over time. The shaking of the boat on the bend before the main drops is pretty violent, not sure if it's supposed to be or it's just a by-product of the boats not being the right ones for this ride, but on a 'heavy' boat it was very noticeable. Back row was hilarious waiting for the reaction of the aforementioned soakings to those on the front. Other than said amusement, I don't find the back row a very pleasant ride, as you are lifted out of your seat (yes, airtime on a water ride) then slammed back into it at the bottom of the drops.
After each ride we hurried back round as quickly as we could with sopping wet clothes & squelching shoes. The staff must've thought we were crazy, and they would be right. On a few rides there was not a single person waiting, most were just one boats worth of queue, and just on the last few there were 2-3 boats worth. On a couple of those we were lucky to be called forward as a 2. Time was against us for 20, but we just managed to squeeze in the 18th ride right before the gate was closed. Absolutely nuts. The reaction of those outside looking at us was very funny, some of them had been on once and were visibly annoyed at how wet they were, wringing out T-shirts and tipping water out of their shoes, whilst were were in an utter state and didn't care one bit. Always funny watching people board the boat bone dry, some not having a clue what awaited them. I can't say that getting changed in a Velvet Coaster toilet cubicle was that much fun, but it was worth it. My shoes and lightweight clothing weighed a ton afterwards. I am sure there is someone crazy enough to have done more than 18 rides on Valhalla in one day, but it was good to smash my previous record of 6 - that day it was quite cold, with longer queues, and I felt I'd get hypothermia if I stayed on any longer. It is a pretty excellent ride, I must say.
