If we were to choose one place in the U.S. to meet, Minneapolis is the best choice IMHO. It's very reasonably windsor casino hotel priced, easy for many to get to and the hotel has adequate space for us (even back when we had many more attendees). Personally, the weather is not critical to me, since I spend the vast majority of my time in the hotel meeting rooms, so I'm very happy if we meet there in March and November.
I've never been to an IETF meeting where the plane fare has exceeded the hotel cost for a week. Caveats to that are that I have mostly gone for IETF recommended hotels, so may have missed particularly cheap hotels, and that I have only been to North American and Europe (but that statistic includes Vancouver and the even further away western US cities down to San Diego). And of course I fly economy, and it's much cheaper including a Saturday night in your trip, even at the cost of an extra night in a hotel (at least it is from here). An almost exception was Paris this year where I was staying fairly cheaply, but that was a cost-shared trip between me and my employer, and I didn't fly (I went by train - though that's not cheaper, just better). Paris has cheap(er) hotels and a metro I understand, so I felt less location constrained.
Dublin's problem was that the venue was isolated from the city. This has also been the case with e.g. San Diego. (I'm assuming no personal car.) Contrast with Minneapolis (and several other places) where you were right in the city. Being in a city is better windsor casino hotel for lunch and dinner options, taking a break to go to a bookshop (or to buy something you forgot to bring) and so on. (I'm deliberately not including tourism here.)
However at the moment my priorities to make being able to attend possible would be time (so the closer to me the better - I realise that's impossible globally), cost (hotel first, windsor casino hotel flight second, rest is noise) and the ability to plan ahead to only attend part of the week. This is the current economic reality. Dublin actually scores quite well on those for me.
What about Italy or Spain? I've never heard about an IETF in Italy. I'm ok with meetings outside Italy since i like traveling very much, but i was wondering why it has never been taken into account windsor casino hotel in the past meetings. Is it expensive? I think Italy and Spain are much cheaper than France, UK or Sweden, aren't they?
