Appears to be all open but keep an eye on CRT and ANT notices.
In my opinion, the best place to moor in Stratford is in the Bancroft Basin. If it is full, moor on the river.
Worcester I would say on the pontoon between Diglis (river) locks and Diglis basin, if you can find space.
Otherwise go up the river a bit further and moor near the racecourse (creative fendering may be needed, the side has an odd overhang). Indeed go up past the Cathedral anyway, even if you are not mooring up there, just to see Worcester from the river (before turning and coming back down).
I would do the ring clockwise, the Avon locks are more relaxing going downstream.
