I have stayed at the Newport, breakfast is the same as at the other ones, i.e. a continental buffet. Shame no sausage, fried agg and black pudding .
They supposedly don't let in pack lunches, but in the unlikely event you get turned away with you food there is a left luggage place beside the turnstiles on the right hand side and lockers in the middle. If you come out but intend to go back in get your hand stamped.
Newport is the furthest away of the disney hotels its not that far but you would be best to take watrproofs or anything else and leave in lockers to save treking back.
Know your kids weight in kilos, my son was unwell and I tried getting pain killers from the medical centre, they wanted to know his weight in kilos, I didn't have a clue.
You will usually get in earlier to the park as you are a disney resident make use of this time to go on the busy rides like Peter Pan.
We didn't bother going back to hotel for dinner we stayed in the parks and saw the light parade and the fireworks. Disney can't do fast food, it ain't fast and i am pretty sure it ain't food. In the warmer weather it is best to get rolls from the vendors.
Any more questions and i am happy to help.
