Did the WAW back in June 17 with Nick (GNITS of this parish).
We actually went most of the way around the coast of both Eire and N. Ireland and also took the opportunity to stop off for a couple of days at the Horizons Unlimited event in Enniskillen, where we listened to some really good talks on adventure travels, including one by Mide of this parish on her exploits on the "Road of Bones"
My trip was 11 days in total, as I also stopped off the night before the ferry in the Wye Valley, and then we also did the two days at Enniskillen. I would imagine you could do the WAW in 7 days if time was limited, but you wouldn't be able to spend much of that exploring stuff around the route.
The WAW route features in a number of excellent maps and downloadable routes. I bought the Xploreit book which has all the detail you could possibly need:

The route is also very well marked and signposted so you are pretty unlikely to go wrong!
We took camping kit, mainly for the HU event, but we did end up staying on a campsite for one night as all the accommodation in town was booked out for some big annual event. The rest of the time it was dead easy to find good places to stay. You don't need booking.com, just turn up somewhere at the end of your day, go to the pub and ask there. They often have accommodation above the pub, and if not, then they will phone round and find you somewhere!
The roads that form the route are quite varied, from tiny single carriageway stuff well off the beaten track, to more open and sweeping high speed stuff. The scenery is just stunning, and the beaches were amazing but nobody on them (with apologies my pics don't do it justice).
Due to time constraints, we just rode round it and occasionally went off to a viewpoint, or a to see something of particular interest, but there is so much to explore you could easily turn it into multiple trips over time if you wanted to. The people are also incredibly friendly and helpful and we had a great craic everywhere we stayed.
A trip I really enjoyed and one I wold most definitely do again
