Cheaper Arthur, but by how much?
For me personally it'd really have to be quite a significant amount to warrant driving to DUB, flying via FRA and MUC to get to ADB and the same upon the return. I haven't seen the TCX schedule for 2012, and admittedly if the ADB runs to the same Saturday night schedule as this year, it isn't ideal either but I think I'd still prefer that over the multiple-segments.
Not having a go, each of their own I know. My father is happy to travel via the mainland when going on holiday to save £100 or get an extra afternoon of the holiday, maybe I'm just a bad traveller!
