Yes, her feelings matter just as much but for real, it's also your day. If money is such a concern, I think they'd understand you guys just going yourselves. How much of this would you be paying for? Frankly, I don't think it's fair for you to be footing the bill for people you don't even really want there. In that situation, if eloping just isn't possible, I'd do a very small event in the city where you live, get married, then fly to where ever you want for the honeymoon the next day. That way everyone is included and the ceremony/dinner itself is far more cost effective and you aren't wasting it on flights.
