Download the entertainer app, gives you money off restaurants, coffee/cakes etc, days out, shopping etc.
If driving, visit dreamland waterpark too. It's about an hour drive, but it's so much quieter. When we visited in February a couple years ago, we were the only people there.
Friday brunch at friend plaza festival city, our kids had an absolute blast and there chocolate brownie cheesecake is to die for.
Kite beach is great fun, has rides and an aerial adventure for the kids too.
You can't go wrong with dinner in any of the jumeirah beach hotel restaurants, my favourite ever dinner was from the Dhow and Anchor.
The madinat is lovely for an evening stroll.
Safa park is lovely for a bit of chill time, if you have time!!
Magic planet at Emirates mall is truly amazing.
