I am assuming here, that you foresee a problem with accommodation....

I have spoken to a friend of mine, who has been to Cadiz on a number of occasions during the Carnival and he has never had a problem getting accommodation at a reasonable price.

He has given me some useful websites which will be able to assist you: http://www.cadiz-andalucia.to/ http://www.andalucia.com/cities/cadiz.htm

The carnival is a wonderful experience and if you can, please make it down to Cadiz because it will be well worth it.
