The current AP deal through promoparcs and cemultiavantages is buy a discounted price AP, and get a child's AP of the same type (child has to be aged under 12 when you visit DLP) for 35 euros. There are no free child's AP deals at the moment.
Jill, there is no problem buying child's APs for your niece and nephew, but you need to remember to bring letters of permission with you from their mum or dad if they are not coming along, as DLP will need these, confirming its okay for you to get APs for someone else's children.
I've done off offsite (ie Bussy St george and Val d'europe) and offsite in the associated hotels. I dont mind either, you just have to be a bit more organised with your timekeeping for off offsite, to get the trains etc in and out of DLP.
My DD prefers the associated hotels, for some reason she has no issues at all with the shuttle buses to and from those hotels, but she's not keen on the train stations and the ticket barriers there.
I think its just what you're used to though, in my case we travel all over, by car, bus, plane etc, but she's only been on a train a handful of times in her life.
As Jill says, regardless of where you are staying, you can visit any/all the onsite hotels, to eat there, check out the gift shop, bars, and public areas. This includes taking part in the morning character meet n greets

- we did that at the HNY on a trip where we were staying at the Explorers one year, and nowadays we pay for breakfast at the DLH one morning, and so see the characters who are milling around the hotel then.
