I hope you get sorted out!
found this re advertising holidays on CAB website.
Your holiday was not as you expected
Your holiday may not be as you expected because of:-
"¢poor accommodation
"¢the facilities at the accommodation or resort were not what you were led to expect
"¢the hotel was incomplete
"¢the resort was not as expected
"¢the surroundings were noisy or dirty, for example, the hotel backed on to an airport or building site
"¢the holiday was not as described in the brochure.
If the holiday is not as you were led to believe, you will be able to claim compensation.
***However, If the holiday was not as you expected because it was different to publicity material you have seen or to an advertisement, you may be unable to claim compensation. This is because publicity material and advertisements do not form part of the contract you made with the holiday company when you booked your holiday.****
Descriptions of holidays must be full and accurate. If the description of your holiday was not an accurate one, an offence may have been committed under the Trade Descriptions Act and you should complain to Consumer Direct on 08454 04 05 06.
**** as said above, its the pictures that usually draw you in first

so really its unfair they can get away with that side of things but once it hits the 1st march 2011 the ASA will have more clout when the new rules come in.
