Transport from WDW to US IOA with Happy Limo?

[Desnik]

Anyone use Happy Limo for theme park transportation? We will be staying on Disney property but going to Universal IOA for one day. There will be 5 of us. I was looking on their website and it seems they offer a Suburban for r/t transport for $107. Could this be right? It seems like a great price to me. Has anyone booked something like this with them?
Thanks for any info!
