I have 3 kids twin 1year old girls and a 3yr old. I wanted to know if I should take my twin pram and a stroller or just take 2 strollers as the twin pram might be to big for the walkways? Also i dont really want to take many nappies as that will take up heaps of room. Are the nappies alright over there. Do i need vaccinations for the kids? Any other advise for me about taking the kids would be greatly appreciated.
