Do we have an ADR booking date calculator on our lovely site? Because if we have then I am sure it will be the absolute correct one SO far I have found 5 different ones online. And from them so far I have 3 different dates We arrive on the 29th April 2015. I have been given ADR booking dates of 29th, 30th and 31st October from various different places. So, do I just sit with my trusty calendar with my finger on the 29th April box, and count back 180 days one at a time? I know I can of course, I wasn't too bad at school But do we know where there is a magical technologically-sound online one?
