Children are allowed in the main dining room, but my kids found the menu had very little choice so we ate at the Windjammer, and also Johnny Rockets which is loads of fun for them and has plenty of choice.
Just cruised on Navigator of the seas mind you my children are adults now. I did not fancy the main meal one evening and the waitress said i could have the childs meal burger/chips if the children do find it hard to choose tell the waiter/waitress and they will help in getting a nice meal for the children.also in the windjammer although it is self/service you have a lovely choice of meals to suit everyone.The johnny Rockets dining area is full of life the staff entertain you there.A tip if you go to breakfast in the Windjammer go either early or the latest as it gets very conjested.your breakfast can be cold before you get a seat.
