Our daughter, 4 years old as of a month ago, has been in her current daycare, which has a preK curriculum, since she was 2 (home daycare before that). She's transitioned classrooms 3 times in that daycare (2s to 3s to pre-K/4s and is due to transition to pre-K2 in August, when the older kids move up to K). She has friends there and loves the school.

An opening has become available in a daycare 2 blocks away from my husband's job, and we're trying to weigh the pros and cons. Wondering what others would do.

Pros for the new daycare:
A little cheaper (~$100/month less)
Commute would be easier (3 people in a car would allow us to take HOV lanes to get to and from work faster, probably save us 30 minutes each way)
Closer to husband's work so if there's an emergency, he could easily pick her up without fighting traffic
Newer facilities (current daycare is in a church building that's pretty dated, playground is old)

Potential cons:
Kiddo has friends and established relationships at current school, and there's only a year left until she moves to kindergarten anyway
New daycare is in a government building in DC, so there's higher chance of safety issues (though the police is right there because it's a government building)
If the traffic is bad all around, it's an hour each way in the car with the kid
New center is NAECY accredited, just like our current one, but they are not officially licensed by DC (they say it's because they're a government building, though I'm not sure why this is an issue, and they voluntarily follow all the licensing requirements)
Less outdoor space because they're in downtown DC
