I live in Plantation and my son goes to Kinder care learning Center five days a week (full time schedule). The cost is $165 and includes meals. (It's a franchise and they have two locations in Plantation - one by the Broward Mall and the other on the corner of Sunrise and Nob Hill where he goes)
When I was researching the other places - I found this price to be very acceptable. Adventure Bay was at $150, another very appealing place at Clearly between Pine Island and University (forgot the name) - $165 (meals not included).
The only places that SEEM to be cheaper are "religious" places - I've checked Methodists (the cheapest and highly recommended by my friend - at 70th street by the Methodist church), catholic, Lutheran, and Jewish childcare places. They do have lower prices, however they are open 9 months a year, with a summer camp at the double price. And they are closed on all religious holidays (quite a few when you add them up). When you consider those factors the "seem" word at the beginning of this paragraph makes a lot of sense...
As for the non-religious places - their rate for 3 days a week is only slightly less then the full price (they want to discourage that) - a year ago it was at approximately $135.
