We go to the Growing Place at Meyers and Madison and love it there. The teachers are great, the tuition is reasonable and my kids absolutely love going there. The other parents are great too and we get a lot of friends/playdates/birthday parties etc. PM me if you want more information on this school - their registration is the beginning of February.
As far as Montessori, I don't know why you'd want to go all the way to Wheaton if you live in Villa Park -- work there?? There are plenty of Montessori schools around here - in Villa Park, Elmhurst, Lombard. Also to pay a $250 fee without observing or deciding if that's the place for your child to go is absolutely ridiculous. I actually think to pay that high of a fee is ridiculous even if you wanted to send your child there. All places have a registration fee, but that seems excessively high. Anyway, we went to Oak Brook Montessori for one year in addition to The Growing Place. (on Summit just south of Roosevelt). I really didn't notice that she got anything more out of it than our regular school and it was 3 times as much money as our regular preschool for one less day. I don't think it was worth the extra money in my opinion. I also think that for our purposes - I really want my kids to go to preschool to learn and socialize - our montessori school wasn't the best choice for us - most of the kids enrolled were there all day (8a-6p) because both parents worked outside of the house -- so it was more like an education based day care. Because of that, it seemed like there wasn't any time for playdates etc. and we just didn't become friends with anyone there. For my daughter's 5th birthday we actually invited everyone from both schools -- everyone at the Growing Place came except 1, only 3 people from Montessori came and the others didn't even respond. I'm not saying they are all like that - but I also have friends who had kids in montessoris in wheaton and elmhurst and had the same experience.
If you do go the montessori route, know that all of them are independently owned and operated so they are all a little different - if you didn't get a good vibe at one of them, that doesn't mean that the montessori concept isn't for you - you can just try another one. I wouldn't be paying a fee at all of them though that's for sure. Go and observe and talk to the teachers and then try out another one. Only pay the fee at the school you choose to go to.
I have no idea what TCD is so I can't comment on that.
