Thanks for the info on getting flights re-routed, I was pretty sure they wouldn't be willing to do that, I've tried it on different airlines without much luck.
Here's a copy/paste of the info I've sent to my friends that want to hit up Ibiza....
--------------
Ibiza (the party island) looks like it could be a bit complicated to get to.
FERRY

You would need to take the ferry from Ciutadella to Alcudia, which is the next island to the west. It takes 1 hour, and leaves at 9:45PM, and costs 70 euro.
From Alcudia, you would need to make your way across the island to Palma. It's about 50km. There are buses for 5 euros, no idea if they run at night. A taxi would be about 70 euro.
From Palma, you would take the ferry to Ibiza, and it would be another 70 euro. It takes 2 hours, and they leave at 8 AM.
So, likely, you would need to spend the night in Palma, and leave for Ibiza in the morning.
