Couple places names,

My office friend told me that She wants to go on day trips from los vegas with her boyfriend and She wants to spend quality time with him. She asked me about the best couple places which She can visit with him and propose to her boyfriend. Lack of information I could not suggest that's why I am here to know regarding it from the tourists. So share here places names that will remain best for proposing to her boyfriend, and then I will recommend your shared information with her. Waiting for your fast reply...
