A remote area that can be reached on hoof appearently within a day? How remote can it really be if you can reach it traveling through the wild without hiking gear or tents of anything?
Maybe RD is the exception rather then the rule. Maybe it's not usual for ponies to freak out like that over celebrities.
How do the openly accessible stain glass windows despicting the mane 6 fit into that?
To be fair we dont know how long they traveled since it was Montaged, they might have spent the night in several hotels along the way and the house jsut be that close to the last hotel, not to mention there are trains that go *Everywhere* so it's possible that they spent a long time on the train. (Though I cant dissagree with your logic of them needing saddlebags for any particularily long distance... of course we could check the map and see if there are any other landmarks like canterlot and then make a rough scale...)
As wesh said, look at "Green is not your color" with how the ponies reacted to Flutters when she was a famous model. If publicized, I'd think saving the world woudl get at LEAST as much coverage as a new model would...
Who says they're openly accessible? They seem to be in a 'vault' area since they were visible (and important to the plot) in 201 when celestia went to retrieve the EoH, which were sealed away at the end of the hallway, which I'd assume is a high-security area given the EoH were there.
They have made the correct choice though. The best episodes are the simple slice of life episodes taking place in ponyville. For the sake of realism, they could ruin one of the strongest parts of the series by having everyone treat them like heroes. The mistake is not in showing it inaccurately, but in having episodes that put them in the hero of the state role in the first place.
I think they could play with it a little, similar to how things went down with MMDW, but that would get old and if used much would water-down the episode. (Think about the buildup and letdown in IAT when Twilight was avoiding the guards and was cornered... and they just said "Oh hey, Twilight, let me open the door for you, have a nice night!" except FAR more annoying.) An episode where the M6 are famous and get mob'd by fans everywhere they go would be hilarious --- but it would only be so for 1 episode, or 2 if it was a two-parter. However, I'd think at the least some of their lesser exploits coudl be used, like the aformentioned BYF/Gala incident with Dash, or perhaps a throw-away gag like the M6 trying to get a hotel room and none are left untill flutters 'eeps' and the attendant recognizes her as 'my favorite model ever!' and pulls some strings. Little stuff that makes it feel less contrived...
