I think people staying in the UK for their 2012 hols may be the biggest cause of this. I am amazed by the number of people I know who have booked the Isle of Wight, Cornwall, Great Yarmouth etc. for this year.
I am also learning that there are more places to visit than Turkey - so now can compare what's what better. For this year, 7 days seafront hotel (inc breakfast) - decent 3/4 star standard with sea view - Fethiye £288, Portugal £676. Very comparable hotels and locations. No comparison, around £400 cheaper for Turkey. Sadly, the flights for us are something like £800 more from here to Dalaman than here to Faro. So Portugal it will be this year and we are just four bums on seats each night - but if there are ten families like us going elsewhere then that is 40 bums on seats - equivalent perhaps a whole empty restaurant on Calis prom - and I bet (sadly) it's more than 10 families.
Last year we went to Spain and found it to be pretty much the same for eating out - one thing they do well in both countries is cater for all budgets - like Turkey, we found you could eat in beautiful restaurants but also get well fed indeed for a few pounds. We also found the locals very friendly, like Turkey.
We can't stay away from Turkey, just like so many members on here - but we don't need to choose it and that, I fear, might be the biggest problem the Turkish resorts will face in the coming years. To love Turkey, obvious as it sounds, you need to go there - and I do wonder if people are going to miss the opportunity to fall under the spell, by choosing Spain or somewhere else instead. The truth is, it is us idiots who fell in love with the place that pay the ridiculous flight costs year after year. People not coming means no "year after year" types being created to keep the numbers up. Nobody wants Calis and area to have a great season more than me and I do hope it happens.
