We had a fabulous trip to Bremen in May of this year - I got some good advice from PPRuNe before I left here:

Although we planned to go to Lubeck, we ended up in Bremen due weather at the main airport - very easy approach, and great services and cheap! I totally recommend them.
If you are looking for some interesting flying, consider routing via the Fresian Islands (e.g. Texel) in Holland, and follow the island chain into Germany where it becomes known as the East Fresian islands and I can recommend you consider stopping e.g. at Norderney (or one of the others - we didn't have time for all of them!
)
Best,
