Plan to enjoy a tour,

My sister's boyfriend selected the east coast america tours for both of them. My sister is excited to enjoy this trip with him. She needs your suggestion about the special places which are only for couples. So if you know about it then share it here. I would like to recommend your suggested places to my sister.

Your sister's planning is very well. I must say that these are places amazing for new couples. I have described these names for your sister.
Franz Josef Glacier,
Hokitika Gorge,
I highly recommend your sister go there and you will enjoy all moments. Must take the camera with you.
By the way, What is your next plan?
