We are taking our boys (7&9) in March, staying at the Hard Rock Hotel, planning to go to Waterbom and possibly New Kuta Green water parks and also the Bali zoo, any suggestions for other 'fun' stuff to do with them would be much appreciated. Also they are into Monster hats and Nintendo 3DS games so any info on best place to purchase these and what we can expect to pay would be great too. Thanks.
