We are going in June. The two families we are traveling with have never been to Disney so they have no idea what to expect. There are two teens,one tween (who is severely autistic), a four year old, and a five year old. We want our own room but we would like to be at the same resort as them. We also want to be on the Quick service meal plan.
That makes it a lot easier. I wan't trying to be nosy, honest. What I would do, and this is strictly my opinion only is I would sit down with them and discuss budgets 1st. See where they are on resorts etc.
I would book my own reservation and help them to book theirs. Once they have a reservation number you can call WDW and have them link your reservations.
As far as meals go, on QS I am assuming that you won't be eating A TS meal every day. For the character meals I would let them know ahead of time and tell them the price and ask them if they would like to join you if they can afford it. If they can, great, make reservations for everyone. If not, that's okay, too.
For the parks/FPs I would again, sit down and talk to them. Direct them to various planning websites and encourage them to get the "The Unofficial Guide." Find out their "must dos" and "won't get nears" and then schedule FP for the things that overlap. Help them schedule any other FP.
What we usually do in regards to touring when we have gone with other people we let them know what time we will be heading out in the morning. If they want to meet you fine, if not they can meet you in the park for a meal or your 1st FP together, but I would make it clear that you are going at whatever time and won't be waiting. I think this gives them the opportunity to go with you, if they want, or opt to get an earlier or later start. ""Hey, we are heading out at 9 tomorrow, if we don't see you at the bus stop, shoot us a text when you get to the park."
We also usually make a plan to meet for dinner, but we usually do 1 TS a day. I guess with QS if you have a plan of where you are going to eat you can say, "meet us there."
