I'm a little confused about what the 180 would be- would it be saying you guys don't have enough money, or bringing up the topic of finances? (Sorry if I've missed this is previous posts).
I'd say (IMHO, and either way) don't raise the issue on money for the Poland trip with H. Leave him to make a move on it and if he brings it up again send him the budget and let him make the decision about the availability (or lack of) funds for it.
Wroclaw doesn't sound like the funnest place in the world, but great news on the flat abs!!
