Hi there!
I did not have bridesmaids...I had a bridal party of 'dudes'. A dude-of-honor, best dude, etc. But, what we did was pay for breakfast the day of the wedding (he paid for all the men including my dad & i paid for the 2 moms & 2 other girls attending the wedding). We also paid for everyone to attend a Mickey's Very Merry Christmas Party in the Magic Kingdom. We figured this would be better especially since some people were tight for money going to WDW for the wedding. We also had welcome bags waiting with beanies of the 7 dwarfs for the wedding party.
I am not sure if you are having your wedding in WDW so this may not help you at all but if you are then maybe you could consider treating for some kind of meal or something. We liked this idea because people were already spending money to get there and stay, the meal & party tix were worth more for them. We also paid for other little things here and there. I don't know if this counts but we also did an illuminations dessert party and everyone pigged out. I highly recommend the illuminations dessert party!! So, there were alot of things we did throughout the 5 days period for our guests & bridal party as opposed to just giving them each one gift.
Just some thoughts based on what we did....you have to do what feels right to you.
Have A Disney Day
