I was about to suggest the Hotel Portmeirion, but have just checked the prices and am still shaking and sweating.

Is there something to be said for having the affair somewhere within reach of public transport, as for those of us who don't drive, taxis can really add a bit of a premium. Possibly (and aptly) on a branch line someplace?

Thanks all - and yes, rab, I did just that.
OK - already there's a possibility - Brownsover Hall, Rugby [where the M1 & M6 meet] which is a gothic mansion! Nice people. They can accommodate us on May 15 or May 29 [unfortunately they have a very large wedding on May 22] for a group rate of £35 per head which includes full English breakfast. Also a bonus - NO single room supplements for those that would rather snore privately. There's a choice of two private rooms we can use as well, both near the bar [Boddingtons, Flowers - dunno if they're crap beers or not]. There IS a smallish wedding on the 15th, so we shouldn't be too conspicuous by our jollity. No deposit needed - just a written confirmation from me.

Cor, sounds great. I'm in for any of those dates.

Bread] I prefer the phone co-op because it is owned and controlled by its customers. I've had more problems with both 118118 and 188888 than 118 114, and it is cheaper than both.
