1-Daily activities:

2-How long in a day/TT:
It typically takes me anywhere from 1-2 hours to play through a day. Sometimes more if there's an event or w/e. Yes I do TT. I TT to the next day when I feel like I've done everything I wanted for the day. But I never TT more than one day ahead, and never TT backward. On average, I probably go through 2-3 days per day.
3-Fun things to not get bored:
Well I TT to the next day.

That keeps things new and gives me things to do. But otherwise, I visit dream towns for inspiration sometimes, or go to the Island to fish/catch bugs. If there's something on sale at the Island that I want, then I play games to earn coins.
4-Ordinance
In my first town, I have the beautiful ordinance. In my second town, I don't have one.
