I was having a discussion about this last night over some dinner with friends from work. We actually tried to transport ourselves back to the late 80's and think about Little Mermaid. Basically, we determined if the management of today were back then, Little Mermaid more than likely would have been put in TLS. It would've been a great move business wise, spruced up the area and brought in more visitors. And there'd still be the same level of arguing over that decision.
We talked about it for a good long time and really, we got into a nice debate over the whole thing about it. And if WDWMagic Forums had been around I think we might have been making the same points. None of us could've seen the staying power of Mermaid back then. I'm not justifying a bad decision (trust me I'm not, I hate Frozen and EPCOT is the favourite park [see my post on it's 25th anniversary were I had it tattooed on me]) but I can see all the temptations there.
I think if they had the choice to move it, it'd move to MK, but MK just had a massive makeover and I think the fallout from basically shuttering it back up in mass sweeps for another so soon would not be wise. I want it out of DHS, but there's talks about keeping it. I don't think it could fit anywhere in DAK, so best bet was Epcot and Norway. So, oh well.
I just wish it'd hurry up and pass. I'm gonna go ride Maelstrom tomorrow and have a good weep. It was a running joke with my ex over the "you've come this vay before..."
