We are looking at going to NZ next August with a then 5 and a half year old and a 13 month old. We are looking at a flight that comes back via Houston and considering stopping off for a couple of days before heading back to the UK. Just wondering if anyone has any pointers of things to visit, we would quite like to go to the space centre but it looks quite far out, good areas to stay and ways to travel around? I've also read that it will be very hot and humid, what are we talking at end of August , 30 degrees? Thank you for any help! :)
