Best case scenario for Pokemon would be something akin to the entertainment offerings at Berk or Jurassic Park, or weird as it is to say, Sesame Street Land at SWO.
1. Between the high-budget and well-executed Raptor Encounter and Meet Toothless experiences, and the walk-around Dino Handlers puppeteers, Viking performers, and Lightbright mechs, I think a very solid and lore-accurate squad of Pokemon Trainer performers and puppeteers could give us some great offerings. Charizard Encounter, basically.
2. I'd also be interested in something akin to Sesame Street Land's meet and greets. They have a consistent staff of fur character performers that do M&G sets two at a time, with about 10+ different fur/mascot-style costumes available to fill those booths. With even more showing up for the parade, individual float show moments, or special events. Having a selection of meetable Pokemon that large would certainly help ease the lore / theming concerns imo. The costumes already exist in other parks, and it's the only way I see us getting more obscure Pokemon like Geodude or less relevant starters included at all.
