Have a big anniversary coming up in March and would DH and I would love to do a self-guided tour using a tour company to provide bikes and lodging and maybe portage. We think the weather would probably be bad in March so would like to go in May perhaps to miss the summer crowds. Initially we consider the old sod- Ireland or Great Britain. But I would totally consider Denmark or Belgium or somewhere like that. Copenhagen is on my list of places to visit someday (and they even have cool daily bike/train rental combos).

I looked at Greece and it's a lot of money.
NZ is a possibility but but the flights are really long and expensive (but fall weather in March).

Any ideas?
