We stayed there about 8 years ago. The park itself is rather odd and a bit dated but OK if you like quirky things. It is probably best suited to younger children. The Coombe Martin Wildlife Park is up the road which again is rather unusual but we had a good day out there.
I wasn't mad about the local area and, from memory, it was quite hard to find anywhere decent to eat. For beaches we travelled to Woolacombe and Croyde and if we went back to the area we would stay nearer these (but then we do like going to the beach most of the time when on holiday).
What do you like to get from a holiday? Have you thought about North Cornwall?
Thanks. We have been to Bude and it was lovely but it took 9 hours from London (admittedly with 3 breaks, on a Saturday in August). But then Ilfracombe probably isn't that far off that, either... Beaches are not a priority for us, but I did think north Devon might be less crowded than Cornwall or south Devon in the high season?
