Need help planning a proposal at Mt. Rainier on Oct 17th Weekend

Hey guys,

Need some advice from people who know better:

I planning to propose my girlfriend at Mt. Rainier Area on Oct 17th (Saturday)

Can someone please help me with following information:

1. I’m planning to propose in the evening @ 5-6pm in the rainier area. According to you what would be the best area for the proposal? I’m thinking paradise - along the Myrtle fall trail around 5.45pm (will footfall be less during that time?)
2. Will fall colors still be visible during those dates - in paradise?
3. Will tipsoo lake or reflection lake or sunrise would be better?
4. Any road or park closures I should be prepared for during that time?

Looking forward to hearing from you! Thanks in advance.
