Hi N.!
I'm not sure which one you wanted to go to, but the ones I'd recommend are:
Little Turtle Preschool (23 & Card). This is where my son goes currently (he just finished the 3-year preschool program and will be going next year for the 4-year program.) We both LOVE it.
Dakota Preschool (this is located inside Dakota High School). I thought this was a nice preschool as well, and it literally costs half of what Little Turtle Costs. There is one teacher in each room, but then there are also about 4 girls (high school seniors) in each room to help out (they get credit for this "class".) I thought that was pretty cool. We chose not to go to Dakota though, because I needed a morning class and they started at 8 am...too early for my family! (Little Turtle has a few different start times to choose from, I believe they are 8:30, 9 and 9:15, depending on which teacher you want.)
Immanuel Lutheran Preschool: I see somebody else recommended this as well! I did not even consider this school because I was naive thought you had to be Lutheran to go there (we are Catholic). I found out later that I was wrong! I know 2 people who've enrolled their kids there and they loved it!
I'm sure there are openings in many schools still. Good luck!
