After liaising with the Malvern activity centre, the decision is that the Malvern trip will be postponed.
This is on the basis that:
The possibility of beginning the trip later in the week throws up its own set of problems, plus the staffing issue at the activity centre is likely to stand. Rather than accept a shorter trip in grim conditions, it is better than children gain the full Malvern experience in January or February. The rearranged date will be directed to participants when it is known.
