I live in the UK and in April of this year, I booked a diving trip from San Diego, CA, US for September 2014. The Schedule was advertised as 6 nights (4-10 September) at a cost of USD 2,995.00 per person. The company is now claiming the trip was mis-priced that that we must reduce the trip to 5 days or pay an additional $500 per person. This seems very unfair. Is it legal for them to do this or should they honour the trip as described on their website when we booked?
