Appears you've seen a similar site that's 'earning 1k a month', and decided because your domain isn't any different your's is £x,xxx.
Every domainer offers that line of reasoning, but take a look around, hardly that much evidence of people buying into that reasoning and for good reason.
I don't think ChristmasInFrance.co.uk is worthless, it's actually a nice little niche idea but the sheer workload involved to turn it into a proper earner probably runs into hundreds of man hours and quite a bit of financial investment also.
Your pricing as if you've done this work [I've thought the same way in the past but it doesn't wash, so not having a go at all]. As a stand alone domain I'd price it low £xx, if you did the work, presented a credible quality web on it, got some traffic in, and if you set up all the cms, plus set up the affiliates THEN you could be looking at £x,xxx but bare in mind it's a seasonable web probably only in business for a quarter of the year and that counts against it too.
From what I can see [newbie too], no one is buying hopes and dreams anymore, everything is valued based on guaranteed earning potential [i.e Loans.co.uk would find buyers queuing round the block], or work done on content plus domain and/or actual income.
It's a long shot but that domain sounds like a half decent marketing campaign for a travel agents, so could go that route, but won't be easy there either and wouldn't bet on it cos it's far easier for them to simply register XmasInTuscany etc than pay you £x,xxx for yours. These people appear to prefer chucking money away on TV/Radio ads than a good traffic producing domain name.
Hopes and dreams domains are struggling to fetch even £xx. When pricing a domain name it's best to think of all the reasons no one will want it, with as much enthusiasm as you think about all the reasons someone might want it.
Hope this helps and with it was written with that intention.
