Berlin and Krakow
 

We will arrive in Berlin on July 23 and need to be in Copenhagen by 4 PM on the 28. What I need are travel and hotel recommendations. I would prefer B&B's but will take clean hotels. I am shooting for around $100 euro (is this unrealistic?).
I assume we will be traveling by train. We have always used rental cars but I am told this will not be good for Poland.
Anyway, thanks in advance for your knowledges and sharing your experiences.

For a hotel room, try www.hrs.de. Have used it many times and was always pleased.

Easyjet offers cheap fares from Berlin to Copenhagen. I'm not sure of the times, though.

On Priceline, I won the Westin Grand in Berlin for a bid of $61 USD + taxes/fees for July 18-23 a few months ago. You can probably get something for a similar price, but perhaps not the Westin.

Thanks for the tips.
I am having a little trouble with the Easyjet price from Berlin to Copenhagen. Is it 3 euro or 300 euro plus other?

The Berlin-Copenhagen EasyJet tickets are indeed less than 3 Euros plus taxes and fees, for a total of less than 20 Euros each.
