We did the tonga seal experience, the company run a well run ship, the boat was full, it was all very well organised and the views up there were stunning. I thought the seal experience ( we saw about 3) was rushed.....would have liked more time to take photos and properly observe the seals. Overall a fantastic experience but given the seals you can see from land all over the south island, which in my opinion is far better as you are not rushed and I saw far more ( for free) I would not do this tour again. That is no reflection on Wilson's though,,,,just our opinion on the type of activity to choose. Able Tasman is absolutley stunning.
