We've booked flights to Bali for 2 weeks Easter 2015 and finding it hard to decide where to visit, too much choice! If we book the first few nights -definitely decided on Ubud and Sideman and probably Amed. Can we then decide when we're there or will availability be a problem? Thinking either Gilli Air but concerned about the boat that time of year and don't want to waste more travelling time by flying. Or South - Sanur or abu kit region.
