I prefer number one of those, too....
I think GG's point is an excellent one and not at all thread creep!
Athough it's true that the name doesn't have to be the same as the website, it's a plus in my view - one less thing for guests to remember. If you do have a different name, you should probably try and keep all your online promotion based around the domain name, or you risk diluting your google rankings.
If you can get a relevant domain name, it's a great start to achieving high positions in Google searches for several different reasons, as well as instantly giving people a bit of an idea of what the place is like. It's not the whole story of course and everyone's case is different...especially as your own geography, tourist attractions etc etc influence what people search for.
For what it's worth, our considerations were:
We wanted to keep the word Chalet in the name (some people don't do this, but I felt is was important as explained above)
We didn't want anything too snowy as it's a big summer destination too.
Then we considered names that would be unique (at least within the Chamonix Valley) and relevant to people looking at the house, and would suit it well.
For instance there must be a thousand Marmottes and Gentianes in the Alps!
Chalet Praz (the village) - already gone, and anyway there are quite a lot of Prazs (grammar??) in the area, so might be confusing.
Chalet La Flegere (the nearest lift) already gone
Chalet Dru (a very beautiful peak that dominates the view) Already gone
Chalet Mont Blanc - Confusing as Mont Blanc Lodge is close by. Domain name taken anyway
Chalet Les Bois - Already gone several times over (it's the next village along)
Chalet Les Sapins, Meleze, les Sorbiers (various trees) - no-one would remember these, I think, apart from maybe Sapins and there are a lot of places calles les Sapins
Chalet la Foret - perfect!
Domain available (slightly to my surprise, as there are a few others in the Alps, though none near us).
Suits our wooded setting, it rhymes, it's an easy word for non-french speakers, though some people have been known to say La Floret (like a bit of cauliflower, perhaps?)
Finally it's a bit of an insider joke to me as it's the name of a world famous and unbelievably trendy shop in Tokyo's Harajuku district
