at our PEP Pilot lunch is not a thing. They have a snack but not a meal. At the IEP meeting be sure to request bus. You can also indicate preference for AM or PM, but you can get a far away placement, so the bus ride might be rather lengthy. Also, at 3 he is still pretty young, some people opt to attend PEP not 5 days but 3 or 4 days a week - this needs to be written into IEP.
We ended up in 2 programs (PEP and private one part time) and a nanny to shuttle, since private program is too far.
