We are flying into Amsterdam next March, arriving Thurs. March 8 and leaving Mon. March 19. The main goal is to visit our daughter and son-in-law who just moved there, but they'll be working during the week so we have 5 days to go elsewhere. I was looking forward to visiting the open-air museums but it turns out Zaanse Schans is the only one that will be open during our visit. Also Keukenhof doesn't open till after we leave. Oh well; these dates worked best for us so we'll just make it work! We're primarily interested in history so of course will be visiting the Resistance Museum and Anne Frank House in Amsterdam. We're not really city people [especially my husband] or art museum lovers, though we'll probably do short visits to some of the top ones.
Other than a few days at the start and end in Amsterdam to see the kids, we are open to suggestions. I'm thinking about a few days in Den Haag [we may stay with some friends of friends there], possibly including day trips to Leiden and Delft. We could rent a car to see smaller villages and towns, or just use trains to get around. We'd like to stay in the Netherlands this trip; I'll be back in the summer and will be adding some days in Belgium to that trip. Netherlands experts, what would you suggest for mid-March touring?
