We are visiting Singapore for a few days next year. As I worked in Indonesia for a few years 30 odd years ago it would be nice to catch a ferry from Singapore for a day trip to one of these islands. Happy just to have a decent meal somewhere nice and then go back. We thought Singapore to Tanjung Pinang would be the best. Has anyone done this? What are the visa requirments to enter Indonesia on a day ferry trip. We are German and British.
