we are a family of 4[aged 48, 44, 15,13] from India. planning a leisure tour of 13-14 days of NZ [both islands] in latter half of May 2013. may be a night or two at worthwhile places. so a few queries: 1. is the time right? 2. which places should be visited? 3. what is the best mode of travel? thanking in anticipation.
