dude..you're lucky. I'm actually headed there in 2 weeks and I can't wait.

I've been there a few times and although I'm no expert, here are few things to check out

my fav red light district coffee shop:
= Baba. It'stouristy, but it's comfy
- Hill Street Blues - not a great place, but they have this stuff called 'Buddhas' Sister' which is really good stuff

fav all around place
- Abraxsis...outside of RLD, near Dam Square. great place, especially if you like to eat it and not smoke all the time. shakes, brownies etc.
- Grey Bar is good too...good place to buy.

We rent a houseboat and stay there. it's like an apartment, and a great thing especially if you've smoked. I would highly recommend it.

Not sure what you're into, but if you're into food and trendy places check out Supper Club. Also after you've smoked, go to the Japanese Pancake House....incredible

If you like the rav and nightclub scene check out Escape Bar and Hotel Arena

If you like beer be sure to tour the Heineken Brewery. It's cool and beer is good.

It looks like you have time....get on a train for 30 minutes and head to Utrecht. It's an incredible city north of the dam. sunken canals and guess what...coffee shops. you'll love it.

have fun. it's a great city. be sure to get out of the RLD...there's a lot to see in Amsterdam and it's one of the most beautiful places on earth.
