We are planning an extended stay in Wanaka (2-3 weeks in March/April) and would like to find some inexpensive self catering in the area. Are there many holiday homes there? Any website to consult before the trip? Should we book in advance or something can be found upon arrival? Second option would be preferable since we are not sure about the dates. Does tourist info center help with accommodation search? Do they charge any commission for that?
