Is it really that bad if Festhaus Park becomes more Germany? I get the desire for a new hamlet, and I share it. Additionally, I question whether the park really needs another awkwardly-accessed third section for an existing country, a section which probably only has one ride in it, at least at first. They just did that with Pantheon. But I think that approach actually makes more sense in Germany and probably shouldn't have been done in Festa, rather than the opposite. ("Neither" is also an option, but not realistic IMO.)
When Drachen Fire stood in Festa Field in the 90s, it just made sense that dipping into the corner between Festhaus and the bumper cars would take one to more Oktoberfest. It simply felt like more Oktoberfest. Very natural. It didn't suck at all, even if the ride itself kinda did.
If BGW puts in a world class ride back there rather than a one-trick pony, but they don't also spend the major extra dollars to make it an entirely different hamlet (and yes, it would be major extra dollars to create something like e.g. Spain), why would that necessarily suck? I'd still be thrilled. I would just as soon see the existing Rhinefeld area become Austria or Switzerland than wish for Festhaus Park to become something other than Germany, with that weird access corner next to the Festhaus which now would have a big "SPAIN" or "BELGIUM" or "GREECE" or "FINLAND" sign across it. It isn't a particularly great portal to a completely different country.
I might feel differently if there were a train station back there, and if the Festhaus Park entrance could be truly opened up without banishing the bumper cars from the park completely, and maybe if there were a new walking bridge from Festhaus Park to Italy, and... but again, this all adds major cost to an already expensive idea, and I'm not banking on any of that happening. Especially not these days, and especially in light of SEAS's apparent current strategy.
So if, for example, a fantastic dragon themed RMC were to go into the Festhaus Park/boneyard area using Drachen Fire's station, and the theme of the area remained Germany... well, at least the station and setting would probably be far better than the guest-facing experience in Festa Field. As there seems to be little evidence of appetite to add major "forever cost base" to the park unless it's a thrill ride, and as I'm not sure it's even wise to add a bunch of completely new infrastructure now/soon anyway, I'd take the new ground-up RMC Drachenstein as a major reason to celebrate.
And over in Rhinefeld Switzerland, the Burgermeister thing could be kept, and a similarly structured chocolate-themed upcharge experience could be added using the same space at alternating times, so there's greater utilization of that "speakeasy" build-out for the entire family. I dunno. Different thread.
