I don't even know where to begin. I will talk to my DC about how long the kids can stay there, but want to have a little more info so I don't make myself look bad.

I know that I want to enroll the kids in kindergarten when the kids are each 5, and that my main priority up until then are for them to play. I think kids learn best through playing and being active/interactive. We have limited financial resources. I also assume it's inevitable that we'll be dropping the kids off at two different locations at some point.
There's a free preK program here for 4-yr-olds, but not sure what kind of programming those sorts of things offer and what kind of environment they would be in (I don't have high hopes since it's free). It's probably paid for by our school taxes and part of the public school system. There's also a private preschool and preK through a local museum which I bet is awesome, but probably also expensive.
So - what is montessori? What is preschool? What is preK? When do you transition a kid out of DC? What are good options when finances are limited? Any advice on what questions to ask as I look into our options?
Re: SWMR - clueless about daycare, preschool, kindergarten process
Montessori is pretty much exactly what you described you are looking for. its an emphasis on independence, freedom (within reason), and respect for a child's natural mental, physical, and social development.
Pre School starts as young as age 3 and goes until 5 (or kindergarten). You would have to visit different schools to see what their curriculum is and if its a fit for you and your children. We have a co-op in our town thats very inexpensive but parents need to volunteer their time as sort of "payment." All the others are private, as is Montessori.
Our daycare goes until Kindergarten, and then also has an after school program. It is your choice if you want to leave your child in daycare until they are ready for kindergarten. Our daycare curriculum evolves and develops as the kids get older, so they do more structured play/projects/actual learning even in daycare. I think if finances are tight, I would keep my child in day care, especially if you are happy at your center.
As far as what to ask: is there nap time, are meals/snacks served, what is the educational background/experience of teachers, what is the educational philosophy of the school (if not MOntessori, because then you would know), is there a lot of active play to develop gross and fine motor skills, how do they handle discipline.
To avoid 2 drop offs this year, we took DD (2yo) out of daycare. We have a nanny to take DS to/from school and take care of DD.
I am torn on what to do next year. We could keep our nanny and just put DD in a PDO for a few hours per week. Then I could send her to public preK at age 4. I'm excited about the public program (play based). Or I could put her in Montessori for 2 years, but that's $$$.
I don't think there's one right answer. DH and I try to do what seems best for our family as a whole, rather than focusing on what might be our first choice for each child individually.
Sorry, can't help with when to transition out of daycare. DH and I have worked opposite shifts for most of our marriage, so we rarely used daycare and have no basis for comparison of the transition from daycare to school.
