For a wedding at home I would give between 75-200 depending how close I am to the bride/groom.
Now a wedding in JA is different and would depend on what expenses were covered by the bride/groom and what my out of pocket expenses were. If I had to pay for an unplanned trip that revolved around a wedding then my presence may have to be their gift. If they picked up some of the costs then I would try to offset as much of those costs or more if I could. It really comes down to your financial situation and how the trip and it's cost fits into the big picture. I personally would not expect a gift from anyone that traveled to JA on their own dime to be part of my wedding. Their presence and me being able to share JA with them would be gift enough for me.
I left $5 a day for housekeeping and I think $10 on the last day.
That's my 2 cents
