I know baggage solutions has been a discussion point on here for a while and I don't want to just come from a personal perspective but I think some of the solutions being suggested over the years are over thinking a solution to a problem that's maybe not as big as is made out?
Towers has always had similar baggage solutions to now. There were times when they didn't design rides that necessitated a staffed baggage hold costing money to staff all day. Nemesis, Oblivion and Air have always had the station baggage holds and have acceptable throughput if operations are running well. Thirteen doesn't seem to suffer much having one on the platform. The Smiler and Wickerman would as they usually seem to have trains stacked and this holds the dispatch up. I wouldn't want an ugly baggage hold ruining the excellent Wickerman station either so maybe a locker room replacing their baggage holds?
But I honestly don't think there's a need to whack ugly lockers all over the place. When I don't have the family in toe, the only things I carry with me is my phone and my car key and nothing else, both of which I secure on my person and take on with me. If I have the family, my partner will bring a back pack with us with some drinks, snacks, perhaps some sun cream, antihistamines, paracetamol and sanitary ware. Whoever has the bag goes through the air gates first and places in the baggage hold whilst the others sit down and pull their harnesses down.
I see most other people when I'm out and about traveling light as well. Think about what kind of high value things you would possibly need in a theme park? For the majority of guests, it's simply a mobile phone and a car key which I understand why people would not want to leave in the baggage hold. Gone are the days when you needed a pocket full of change that would fall out on Submission or a wallet stuffed with bank notes. I don't even take a bank card, if I do I won't take the wallet with it and just secure it in my pocket.
Impact on operations is probably the main problem rather than baggage. But many Europa attractions also have the same system and I don't see them racking up massive queues without hideous lockers and expensive to run manned baggage holds everywhere. I queued 50 mins for Silver Star last summer (standard queue here, considered long over there) and the station staff where so concerned with the queue, they called out in German and English to guests on the ramp about to enter the platform to get their bags off and loose articles packed away and where taking them off of us as we walked onto the train and put them in the hold whilst we sat down before checking our harnesses. It was incredibly quick. None of the faff you see over hear with people on the platform messing around with stuff whilst everyone else is waiting to be despatched.
