My boyfriend and I are going to Thailand in March for 30 days and we're not sure how many tablets of Malarone to bring with us. I've been reading that we needn't worry in most touristy locations other than a few islands and regions bordering Burma, Cambodia and Laos, but it's not clear to me if we need to take any while travelling through the Central area in places like Ayutthaya, Sukothai, Phimai, basically the road that leads to Chiang Mai. Any advice?

Thanks
