My bachelorette was pricy! But, we went out of town for a whole weekend, stayed in suites in a boutique hotel, paid for cabs, dinners, etc. It was about $400 per person. Luckliy the girls (there were 12 of us) picked up my tabs the whole weekend.
For FI's bachelor party, one of his brothers didn't drink so they rented a large van to transport everyone for about $75, so it was $10 per person and they had it the whole day.
