We book accomodation direct with disney and flights with ryanair. We are in Scotland and the suppliments on the flights are silly. If you time it right you can get 4 for 3, 3 for 2, free kids etc. Check the site, her Look at great deals and price grids to work out the best times to go.
Newport is a beautiful hotel but unless your room overlooks the lake the rooms are nothing special, clean and bright fresh decor. Furthest away at the other end of the lake.
Sequioa's main building has a cosy feel with huge fires and log effects, rooms are in buildings that stretch out from hotel. I think you can request the rooms in the main building which is less of a walk for breakfast. Again the rooms are pretty standard, like any chain hotel. Quite close, at the park end of the lake.
The breakfast were the same in both really, continental buffet style, crossoints, rolls, cold meats, cheeses, yogurts, fresh orange etc. I think there was cereal. Fill the nappy bag under the table with rolls and stuff for lunch .
