My little brother will be visiting New Zealand for the first time in May 2018 and the first leg of his trip will include Hobbiton ($84), Glow Worm Cave ($51) and Te puia ($125 for Te Po evening tour). I have heard that sometimes prices are cheaper when booked on the spot, especially in colder months (can't recall where I read that). For a trip in May 2018, will it be cheaper to book online or on the spot?
In my own trip to NZ back in 2013, I managed to save some $ by booking a one-night stay at Distinction Hotel + Hobbiton deal bundle at around $220 :) But apparently now the hotel no longer offers such package. Are there any more economical packages--other than Experience the Trilogy--that he can choose to save money in some or all those 3 experiences? (Experience the Trilogy offers Te Puia day tour and Ruakuri cave at $320 while the 3 tours mentioned earlier only cost $260 in total).
