Feeling Guilty!

Hi Girls, 
I’m getting married next year away from my hometown, I’ve done my best to give everyone plenty of notice including save the dates. After a conversation with my bridesmaid, I’m starting to feel guilty about what it’s going to cost my guests to attend my wedding. The guilt started after I came up with a fun idea for my hens night (girls day and a night at a local resort, like a sleepover) the idea means my friends would have to pay some money, my hens will be a good 6 months before my wedding and my friends will again be given plenty of notice. My BM made the statement that while she understands why I want to do my idea, she didn’t see the point of paying x money for something when it was easier to go home, given the money needed to get to my destination and dress etc. This started to make me panic that everyone (other bridesmaids included) would feel the same, I don’t want to seem selfish but I do love my hens idea and I can understand her side as well, I’m thinking yes I could not have the night at the resort as other parts of the day will cost money but I can’t shake the guilt of making people pay to attend my hens as well as my wedding. 
I hope my story makes sense and if someone is/has been in the same situation any advice to help would be great!
