I always find it difficult to get the timings right to arrive at a pub for lunch time. The Staffs & Worcs canal is quite a slow canal and the locks are all individual, not in flights so you may not have time to visit the rock houses. You may not be able to stop for lunch at a pub some days so make sure you have food onboard incase it has to be a quick sandwich while continuing to travel. I’d also load up the boat with a weeks supplies of heavy stuff like beer, wine and bottled water (if you use it). On Day four you may also want to do grocery shopping at Kidderminster as there are two supermarkets right by the canal, which also takes time. Also, don’t forget that you may have to stop for an hour every day to fill the water tank, especially if the crew like long showers.
In Stourbridge there are two Indian restaurants in lower high street with are easily reached from the canal by walking through the underpass, under the ring road
