Re: London Wedding - help needed :)
Posho, I went to a wedding in Radisson on Bath road recently, the venue was beautiful but the catering terrible. The problem hotel's is they're tied up with caterers so you need to check which catering firms they use/allow before booking.
Renaissance on Bath Road is also lovely- you can use Sapna there.
Innaya, when I booked my venue parking was essential, so whilst Dorchester and Natural History Museum are beautiful venues, parking is an issue. But if that's not a high priority for you then both venues are stunning. I do know that you can arrange some parking for Natural History Museum in the neighbouring Imperial Uni, but it's still a walk. If your keen on an historical venuewhy not try the V&A? Or something a bit alternative and book the Science Museum - there's one area where they have a 'star studded' ceiling, it may be the Wellcome Wing. Or how about Kew Gardens?
