There is no requirement that you stay a certain number of days in Canada before renewing.
Definitely, when you return to Canada and visit friends and family it indirectly shows ties to Canada and works in your favor, but this is not a requirement.
Many people (at a border crossing) park their cars on the American side walk across the border, turn around and apply upon entry into the U.S.
Unfortunately, everything is subjective -- them more you can do that works in your favor the better your chances for success. That said it may be to your advantage to renew by mail - remember the cost to renew by mail vs. staying in the U.S., making money for the next year, etc. may be worth it.
Good Luck!
