You’re very welcome, anytime 🙂

Thank you so much for your advice!

We were there in December so Illuminations were at 7pm for us. So we ate before then between 4 and 5pm, got into place for 6.30pm and waited around until everyone was gone for the night-time castle picture before heading back to our hotel for bed. As your kids are older than our son was, you’ll probably find things a bit more flexible than us.

If it was me going on your timetable this is what I would do (feel free to ignore it as well)
For Day 1, I would definitely book dinner in your hotel to ensure you have something secured. You might be feeling tired after travelling so book it for after the parade, allowing time to get back.
For Day 2, I’d book one of the restaurants within the parks, depending on what ones you’d like to eat in. For me, it’d be Pirates of the Caribbean in Disney or Bistro Chez Remy in Studios. With your kids being a bit older, I’d stay in the park, eat and enjoy more rides until Illuminations.
Day 3 – sorted
Day 4 – I’d eat in another restaurant within the park, say the other one which might be top of your list.

Personally, as you’ve got half board, I’d fill up on breakfast, take snacks for during the day/or get a coffee and cake if peckish, and eat around 5pm if that’s when the main parade is on. Alternatively, book for 6pm just after and enjoy more rides afterwards until the park closes to maximise your time there. You can always have another snack when you get back to your hotel. I brought lots with me in our suitcases, and didn’t end up using most of it. We were too busy enjoying rides and doing things to think about our stomachs, plus as most meals were 3-course, we were full afterwards.

We’re going for 4 nights with x2 7 year olds.
DAY 1 We arrive at 2pm on the eurostar so will drop of bags at hotel and head to disneyland park and catch the parade at 5. Will then head back to hotel for late dinner/bed.
DAY 2 See the illuminations which I think arn’t till 9.30 so will book an early dinner…should we book back at hotel (Newport) refresh and go back to park or eat inside park and carry on??
DAY 3 We already have buffalo bill booked for second show at 9.30.
DAY 4 No idea!??
