Quite helpful,with changing my accomodation, although I felt a bit deceived. When I made the booking initially I wanted to stay somewhere else. Based on the website, the hotel I selected had rooms available. After buying the flights, and selecting the dates of the accomodation, The Holiday specialists rang me and told me there was no rooms available at that hotel, Alternate choices were given, but I would have flown on differnet dates to get the hotel I was after.
The website of the hotel that I wanted, should have been updated, so that it showed no rooms were available on the days, rather than accepting my dates.
