We arrived around 2.20 am long after check-in time. We got our room key with precise instruction given prior to our arrival and head into our room easily during that cold wet morning.
Motel room was clean, basic and small but served our purpose of catching some sleep for a couple of hours. Water pressure for the shower was a bit low though.
The park ground was nice and tidy and staff helpful and friendly. This will be a good place to stay if you don't mind basic accommodation. The rate for the flat we booked was the cheapest around that area in Christchurch.
