Xiaokeai,tink u can bring anything into batam.the custom quite relax there.They'll only check ur bag outta spore.n no custom check on batam side. But maybe u can change ur plan abt celebrating on e beach to celebrate by e pool instead,cos e beach quite non-existent. I'm sure u'll go back again.cos its really a cheap n gd n easy to plan getaway. Im planning to go either Vday wkend or 2 weeks after dat oso.need to go for a gd massage.
