I've had many a good holiday narrowboating. Haven't done the K&A yet though. It's on my list. Certainly looks good in your photos.
My next trip is at the start of october. An old friend has just moved onto a broad beam on the Gloucester and Sharpness canal and she's off for a month visiting family in October and I'm looking after the boat. Yippeee. I have it for three weks then have to take it to the boatyard just outside Gloucester where it's going in for a week for a full service before she comes back.
Just a bit of a shame it's a broad beam as i'm limited to the G&S, Severn and Avon. Never been up the Avon so that's where I'm heading.
On my last trip, we picked a boat up at Stratford and ended up in the middle of Birmingham, something I've always wanted to do.
As you say, ditch crawling has to be the most relaxing holiday you can have. Plan your day with the waterways maps choosing you lunchtime pub and evening pub!
