We visited Amsterdam with our three year old daughter, while I was heavily pregnant.
Knowing that we would be having early nights in our hotel room, we upgraded to a room "with a view", using money saved from not using evening entertainment or so many museum admissions.
Our room overlooked on of the ubiquitous squares and we spent evenings eating a rather nice room service menu people watching.
It may not sound exciting,but we loved it and kept sane at the same timeR with no worries regarding baby sitting services.
Is this your business?
