AITA for cancelling my RSVP to a kids birthday party?

Original story

I 27 F and my daughter age 1 were invited to a friends birthday party a few weeks ago for their daughter who is also turning 1. I received a Facebook notification advising the date and time but no location or registry/gift ideas.

I sent a text to her mom Leanne and asked about the location and gift ideas and she mentioned that she wasn’t sure on the location due to cost and she would get back to me with a registry/gift ideas. A few days go by and she updates the event advising that it’s going to be at a local beach but you need to apply for a one time parking pass within 72 hours otherwise the city will put a boot on your car and you have to pay 85$ to have it removed.

The next day I went online and tried to apply but could only find where to apply for an annual pass and the annual pass was almost the same price as the boot. So I sent another message to Leanne asking if she knew how to register and she said she’d check.

5 days go by with no further information so I send a follow up text asking if she had any further information another 5 days go by and I received a text last night at 10 pm apologizing that she forgot to open my message and that I should be able to register through the annual pass link.

I messaged her back and apologized that we wouldn’t be able to make it to her daughter’s birthday this weekend as I didn’t hear anything back so we made alternate plans and wished her daughter a happy birthday. She sends me back an ‘Ok’ so I let it go.

A few hours go by and I hop on Facebook during a break and notice Leanne made a status ‘Nothing is more frustrating than setting up your kids birthday party just for everyone to cancel’.

I commented on the post again apologizing and recognizing how frustrating it is but also reiterating that I wouldn’t have cancelled if she would have kept me in the loop on what was going on with the parking pass issue. Leanne sent me a private message saying that the status was not completely directed towards me but everyone else seemed to have no problem with registering for the parking pass and then made a comment implying that I’m one of her only friends with kids and by me cancelling this was money wasted.

I don’t think I’m the asshole because I see it as if you’re hosting a child’s birthday party it’s your job to make sure guest questions and concerns are addressed in a timely manner rather than week of but I’m open to others perspectives because her friends are telling her on the post I’m an asshole and to never invite us again.
