I think roughly the same - and not just about AI. After years of scoffing at those who let a holiday shop sell them a package, when you can get your own flights, find a hotel and easily book transfers, I must admit I have grown to relove the package deal. We choose our package, everything is sorted by someone else, we just report to the airport and everything is taken care of. Of course I still do my own arrangements for our annual week in Turkey.
We tried Morocco and Tunisia, and this year it will be Mexico - all package and all AI. I would anticipate that this year will be the same. We enjoy the kids enjoying the AI and we get out and about to see the places that interest us (believe it or not we often do the Thomson trips - but also we get into town and book a few boat trips etc without their help).
We couldn't possibly live AI for the entire holiday - I find good restaurants and we go out a few nights - in fact in Morocco we booked a hotel for a couple of days and caught a bus at the bus station which was an adventure to say the least. We obviously still had the AI rooms so at times we had two hotels paid for, the adventure one and the AI one which was booked for the holiday duration. Whilst on adventures we were B&B so researched and ate out lunch & dinner - and fabulous it was too.
And that's the point, one I have made on here for years. Whether or not you like AI doesn't matter. If people who like AI come to Calis/Fethiye and venture out just once and buy one beer - it was better for Turkey that they chose there rather than Egypt or Morocco etc. Our first ever holiday in Turkey was AI andI think it is fair to say we have put a quid or two into the Turkish economy since.
It doesn't work in all cases though. On our (package) coach back to the airport I was earwigging and heard one chap asked a large family group of around 14 people if they'd gone on any of the trips, or visited the marina area. "Nah, we just like to do the pool thing when we go away - we don't go anywhere".
