If you don't like the prevailing opinion, I don't understand why you come on here requesting advice?

$100. per person is the bare minimum. If the venue is a bit upscale, you need to go to $125 or $150.

BTW, there are plenty who will give you advice that $50. is sufficient. If you take them up on it, you'll definitely appear as cheap.

Weddings are once in a lifetime event for people. If you want to attend such an event, you should be stepping up to do so.
