The logistics of renting a house do really suck, and it's definitely something we should look into.
I far, far, FAR prefer the house rental.
Meeplecon was great, but it felt very different from the cons immediately before and after. I got to meet Soppy's mom (who was great), have home cooking (also great), and hang around with a smaller group of people (again, great!), but I DEFINITELY missed out on some of the things that happen simply because you have a large group of people all together in the same place, like the drinking excursion, early morning gaming, late late late late night gaming, etc.
That said, that sort of thing can more or less be approximated if we happen to steal a portion of a hotel's inventory for the DLers.
The need for a big central meeting place is fleeting but, again, being able to herd cats into a big room is a lot easier than trying to convince them to cram themselves into X's room at 3pm. Plus it's nice to be able to find somewhere to wander to where you know something will always be going on and not have to try and PLAN things (and just to reiterate, planning really does not work so well with the DL <_<).
In the end... dunno? Obviously don't want to bankrupt anyone over this, and we should consider making this a little more Organizer Friendly if we want to keep holding it. Various methods to that end -- like opening up a Paypal account into which people who are going can drop a deposit -- are worth looking into.
