You're required to breakout attendant fees separately, as they do for airfares. It can be the same price, but you have to note that.

Re: Translation / sign services, I hope you stick argumentative providers with the bill flyquiet. The ADA is crystal clear that it's up to the facility and event organizer to provide the service or pay for it, so if they want to fight about lunch changes, they can stick it.

Having said that, I truly appreciate when people organize the services that they need or assist me in doing do so for them. I've run a lot of events, and people who want ADA followed to the letter end up frustrating everyone, including themselves. Yes, you legally can choose not tell me in advance that you need a hearing loop in every room of our 50 person charity event, but that isn't going to make them magically appear. Why not just write me ahead of time to ask for the accommodation?
