Give me some advice on my plans

[Jayhawkfan]

Two of my buddies and me are going Europe over winter break
We get to Amsterdam on December 29th and we are there until the January 1st.
Then to plan on going to Copenhagen and Stockholm till the 5 or 6th.

Then we want to do Prague and maybe Berlin or Munich in Germany from 6- 9th or 10th.

Then do u think we can do Rome, Paris, and maybe Barcelona between 10th and 15th because we leave out of Amsterdam on saturday morning of Jan 16th...

We are taking Eurorail everywhere too

any advice would help
