Well, I don't feel like quoting everyone, and I don't remember half of what's been said already, so you'll have to bare with my through my semi-coherent ramblings...
I don't agree with Sabastian, I do agree with Luciro, and I think it'd be cool to get one of those boats with the peddles and peddle around a lake for an hour or so... Wait... Yeah, that was almost the "boating" thing, but not quite... Oh, yeah, $75 for cable is ridiculous...
...Anyway, I think that actually sounds cool, Div. I'd be willing to pay a few bucks for something like that every now and then, just so long as it wasn't, like, a required thing. By that, of course, I don't mean actually required, just percieved as such. Plus, if there was the opportunity for unique items, I'd do it fairly often. I need something to make my character not just background noise for more skilled people. Or, at least, make him a catchy jingle. I understand that these items would likely only look different, but I'm fine with that. If it's unique, it doesn't really matter if it does anything or not.
The issue here, though, is with immersion. It could, understandably, be percieved in the same light as buying game money with real money. It is, after all, paying extra real money to obtain a boost, if only to your own pride. I mean, say someone has a rich character, and their friend says "Hey, I want to go to the carnival that just came into town! Come with me!" Well, their friend would be a jackass for saying it like that, but anyway... If that person was broke in real life, they'd have to decline, and, I think that could be considered immersion breaking. You guys'd have to be careful as to how you presented this, if you decided to include it. Otherwise, it could be a reason for people to choose a different game. Now, don't get me wrong, I don't have a problem with the idea, but I'm sure there are people out there who would. I just think that you'd be less likely to attract roleplayers with this, and more likely to attract powergamers... Hopefully I'm a fool.
Bad ideas to increase people acceptance of the idea:
1: Cut the price down to $2-3, as $5 is the first step up the price ladder. Under that, it's percieved as insignificant, above it it's percieved as a "this could add up" type of thing.
2: Give each player a token when they first start out so they can attend one of these events for free, giving them the chance at a cool item, and letting them decide if it's something they would want to repeat. If it's not, they still won't have any hard feelings, because they'll know exactly what the events are like, and, well, they've done it...
3: Have an in-game lottery where the winner gets to go on one of these events for free. It'll make it seem, I don't know, like you guys are more open with your money. Make you seem more personable.
4: Include a cheesemonger in the game. Even if it doesn't actually do a whole lot, people will love it. That, or let me have a goat at my character's house. If you do, I'll punch the first person I see who speaks ill of the events. Seriously, if I see someone in real life, I'll deck 'em... Well, unless they're a woman, then I'll just scowl. Seriously, I want a goat...
And that concludes my list of (most likely) bad ideas for making the events seem more "player-friendly." Have a safe drive home, everyone.
