Aside from the survey lacking in many facets, as pointed out by other posters, it is also very UK-centric. Travelodge in the US is a different animal than in the UK, and HI in the US is generally of a much, much lower standard than overseas. Ibis and Novotel don't operate in the US, either.

You may either want to clarify as to whom your target audience is or broaden the scope of brands. I'd also recommend a "I've never stayed at this brand" choice.
