Got upgraded from the "villa"to the "cottage" which is much larger. Glad we did as the "villa" does look small. Lovely clean and well equipped accommodation, we really felt relaxed for our 3 nights. Bicheno is delightful, shame many places are for sale including this one.
Don't bother with the guided penguin experience - the penguins walk up from the beach just a few metres from Tidelines.
Do walk the foreshore walk, it's wonderful particularly if the blowhole is going.
