Bought the GrabOne - Had to pay extra $70 because single room not available.
Pros- clean, helpful hosts, good meals provided, nice place for meeting fellow trampers.
Cons- 40 minute ride to crossing. Not good sound proofing between rooms, extra $5 for internet (good speed, VOIP capable).
NEXT time I will drive from Taupo (almost 2 hours) or find a closer place to stay on a day the weather will be nice for the crossing and just use a transfer bus( adventurehq, or other) for $30-$45.More
