So is there any place with relatively low risk to vacation while being pregnant? Beach vacations are out of question? Hawaii also off limits?

My wife and I actually undertook an extreme challenge (at least for us) - No spending month. Well except for weekly groceries. Even that we are aiming to half it. So, I have to pass on all the dealhacker posts with a cringe and a deep .sigh ! Hope its worth it. 4 days down and 27 more to go!
