AIBU to consider not paying for their flights?

[ThePartyArtist]

Planning a wedding abroad - not anywhere glitzy, but where DP is from and his family still live. It is a very low-key plan so far, with 16 people including us (all immediate family).
If we pay for everyone's flights and accommodation the total wedding budget is £4K (about twice what we can afford).
If we pay for accommodation but not flights it's £2k (within budget)
If we don't pay for anyone's flights or accommodation it's £1.3K.
We wouldn't ask for any presents. Would we be unreasonable to ask people to pay for their flights and / accommodation? To be honest I'd feel bad letting them pay for both so would it be ok if we paid accommodation only?
My parents could easily afford their own flights, but my sisters and their DPs are on quite low incomes. SIL and BIL are both students, although DP's parents would pay for them to fly and they would not need accommdation.

Sorry party that probably sounded incredibly harsh.
It's perfectly normal for wedding guests to have to cough up some cash for wedding expenses, I don't think you can be expected to cover everyone's costs.
It's certainly not worth you getting into debt to try and afford to pay for everyone.
Yes, it might mean that you can't have everyone to be there, but I really think you will have to get over feeling bad.
You sound far to nice to start your married life with a debt hanging over your head, especially not a 'wedding' debt.

I think you should talk the whole thing over frankly with your parents. I'm sure they want all their children to be able to come to the wedding. Sound them out as to whether they would be willing to put something into a flights kitty for the less well-off members of the family?

We married in London so paid accommodation for all guests that had to fly in (DH Italian) plus minibus transfers etc. Paying flights would be an administrative hassle. Much easier to block book rooms and let people sort out own flights. Give them masses of notice though so they get cheap flights or better still research flight options and stick in an email. That's what we did and most of guests came out on same flight.

Agree with Alpaca. Have a frank conversation with everyone that you want to come, and explain that paying for everyone's flights and accommodation will bust your wedding budget, but that you really really want them to come. Book the accommodation and flights so everyone can go together (and it should work out cheaper) and ask those who can to contribute instead of buying a present. Will they be able to stay on longer and make a proper holiday of it? Oh, and then don't get into any conversations with anyone about what anyone else paid for!

Amazing how cultures differ. My nephew married in Cyprus we had to book 2 flights, no direct flights from Ireland, hotel accommodation and gave 200 euro present. We paid for all our hotel costs all food etc. I did think, however ,that they should not have accepted gifts!
