Headley Court: Most heart warming and genuine. Staff were (presumably still are) utterly superb and completely dedicated.
A few more which spring to mind.
Akr: Most heart wrenching to leave.
Spadeadam: Most interesting.
Hullavington: Sleepiest.
Kinloss: Most Scottish.
Witt: Best Friday night (the Mally!).
Bruggen: Most forgetable.
