I think they may find that even fewer people come after being told they have to help cover the cost of the room (WTF? THey could cover it before but can't now?)
ANyhow, do you know anyone who knows the hostesses and you can get their contact info? Clearly people are getting in touch w/ them somehow.
This was one of my main points the other day when someone asked about hosting a shower. Don't place conditions on attendance. I'm not even really crazy about the "bring a book with your gift" thing but I do it anyway when asked. I'm not gonna deny a baby a book just because their mom's shower host is dumb.
OP, ask your friend how to get in touch with the hostess. If she brings up the $25 while you're talking to them - "You want each guest to pay $25 just to attend? In addition to a gift and a book? Sorry, no. I'd like to come, but if that's a condition of attending then I'll have to decline."
If she doesn't bring it up, then I would just attend and ignore the matter of the $25. If the hostess asks for the money at the shower - "Oh, I saw that message but wasn't sure what it was about. It sounded like you were asking guests to pay $25 to attend, but I didn't think that could be the case because it's such bad etiquette. But you really are asking that. Huh. Sorry, no can do."
ETA: I just saw that it's a surprise shower. Then yeah, asking her DH is the way to go.
Yeah I think the mom-to-be would be mortified but I don't think anyone will say anything.
They'll tell her afterward. My work bridal shower host made everyone pay $15 for their (and I guess my) meal and I had no idea until people started telling me afterward what a nightmare she was. I was mortified. But oh well, not my doing, and no one held it against me.
That is ridiculous, but it also makes me feel really bad for the mom-to-be and I hope that her shower isn't ruined by something that is out of her control.
What happens if you reply to the evite? Is there a link to click on where you can leave comments? We did an evite for a friend's shower this summer and they could respond/ask questions through the site. I can't imagine any sort of online invite system that has no "reply to" option. That's just weird.
