My husband and I will be traveling by ferry from Wellington to Picton on February 18, 2014. I have been comparing websites that offer tickets and have found some differences in prices (my husband is over 60). We will definitely be taking the interislander because of better choice of times (6:25 p.m.) I am wondering what would be the better website to go through. Experiencenz.com seems to be offering the cheapest price at $123.50 (on line special right now of 5% off). Any suggestions?
