I think that the real "A" list celebs like Dennis Basso and Tova would stay in a really nice hotel, maybe one of the big London hotels in Park Lane. I would imagine that QVC would foot the bill as these guests are flying a long way to appear on their channel and make them a load of money. I used to live in Acton (a poor area next to Chiswick and Ealing) and used to work in Chiswick at the bottom of Gunnersbury Lane. I love Chiswick. Maybe Tova might prefer to stay in Richmond. That's not far from Chiswick at all and is really beautiful. If I had the money I would live in Richmond. Now I live in Cricklewood NW2.
Someone like Alexis from l'Occitane probably stays somewhere more reasonable. Maybe a Travelodge. But I bet she takes all her l'Occitane products with her!
Simon Wilson is another high-ranking guest, but I think he lives in or near London anyway. I get the impression that Tova and Simon Wilson can be slightly difficult to work with and have to be buttered up like a crumpet!
