Tourist Office, Amsterdam
Here you can get Info about trams busses.
The tourist guide and map with public transport system.
also you can buy here 24, 48, 72 and 96 hours ticket think about a day ticket is 7 euros and valid on all trams, underground but only on the busses of the GVB comapny
For tickets for the sights or passes you might need check out the tourist office at the airport first. Saves so much time and hassle trying to find the place when you get into Amsterdam but also you can pick up some good tips before you plunge into your touristy trips out of the place.
I well recommend what i did, buy tickets such as for Anne Franks House Museum from the airport so you dont have to join any queues at the venue - my first few visits to Amsterdam i never got into see it as there was always long queues! this time i bought an evening ticket - the place is open in the summer until 10pm at night!! and a prebought ticket allows you to enter via a separate entrance away from the queues.
Also i checked out bus routes and connections for trips from the tourist office at the airport so i could see just what i could fit in of the things i wanted to see in the time i had. She was able to put together times and bus numbers and trains so i could for example fit in both a bus out to Aalsmeer for the early morning flower auctions and also the cheese market - both on only that Friday.
So save joining all the queues for info in town at the train station etc and get maps etc from there and then free up the time you have if its like me limited.
Why dont you pop into the British Tourism Authority offices in the Aurora Gebouw, Stadehouderskade 2.
You can be on holiday in Amsterdam and while you are there, you can plan your holidays to Great Britain! It's perfect!!!!
The offices have so much info there, a full range of brochures from all the different destinations in GB!!
And while you are there, say hi to Martin! (tell him it was me who recommended you visit!)
Photo is of some croonies from GB, come over especially to promote the North of England. The most beautiful person isn't pictured though!!!! :o)
