I know it is a busy time of year and will be booking ahead hence the following two questions:
a - is there a discernable difference between the two glaciers? The subtext being will I miss out on anything spectacular if I pick Fox over Franz Josef and vice versa?
b - I note that the heli hike and half day leave at various times during the day. Is this just for convenience or are the glaciers best viewed at certain times?
My initial preference is to go with Franz Josef (hence the posting on this Forum) as it will mean not having to 'break camp' unless advised otherwise.
