My (27M) gf (28F) is the Maid of Honor for a wedding in February. Right now we live about 2.5 hours apart and the wedding location is closer to me than her. The drive for me would be about an hour.

Some backstory: I have never met the bride, groom, or anyone involved in the wedding. The only person I will know is my gf. The happy couple are doing a sort of unusual thing where all members of the wedding party will have their significant others at the head table with them. If this was not the case, I would probably not be going since it would be awkward for me to sit with people I don't know. 

Anyways, she is going to pay for a hotel room for 2 nights, and it's close to $300 a night. That's a LOT for where this wedding is going to be. She told me about it, and it didn't really cross my mind to offer to pitch in. She asks if I can help. I offer the suggestion of just staying at my place since it's only an hour away. She insists she has to be there at the hotel since she's part of the bridal party, which makes sense. 

Now, a little background of me and her specifically. She makes more money than me and lives with her parents until I move to her city. She has no bills other than a car payment and helping with groceries. She is smart with her money.

I live alone, have student loans up the a$$, car payment, rent, utilities, internet, etc. So my disposable income is razor thin. 

Because of these big differences in our income, I do not want to have to help pay for a hotel room that I would otherwise not be staying in.

TL;DR: AITA for not wanting to help pay for a hotel room for a wedding my gf is in?
