Take a bag of birdseed with you. We take one and I'm not kidding you, the scene in the evening and morning after putting some out was like something from Snow White.
Deer, rabbits, squirrels, little birds (finches, sparrows, bluetits, others I'm unsure of!), ducks, geese, coots, moorhens, buzzard, heron, woodpecker - all within ten feet of the big patio window, amazing. Saw badgers once too - not on the patio, but in the woodland.
If you want to eat early - BOOK in advance. The 5 - 7pm slots fill up really quickly.
We find, now the kids are older that we can book a bit more activity wise - when they were young, they just wanted to swim and use the play areas and little beach - for free. Now they like archery, laser clay shooting, table tennis, putting greens, crazy golf, badminton and table-football - it has got expensive.
