So apparently "a few days before your visit" is NOT the way to go when booking tickets for the tour. All tours between now and August 10th are sold out and we're only in Dublin 24 - 26 (leave for Kinsale the 27th). The site says they release them online between 9 and 9:15 for that day, but has anyone had any luck with last minute cancellations?
I'm not new to this. I booked our tickets to visit the Anne Frank house as soon as possible, but at least they mentioned that in the guide book. I'd have booked sooner had I had any idea. gah!
