How to get from Boardwalk to Universal?

Not what they have available or prices, but Mears probably has some options for you.

I have always used the site below. they come right to your Disney resort and bring you back. You set up the times and you are good to go. I have used them 3 times now and I have been very happy with them

Interesting question. Please let me know if they do one ways.

Mears is the top transportation to get from a Disney resort to Universal. People do it all the time.

If memory serves me correctly, a cab should cost about $35-$40 one way.

I'd recommend Mears, too. I think it was $18 a person when we were there in 2012 but that was for round trip so it may be cheaper if you only need it to take you there.

So I"m bringing this post back cause I have some more questions. Is Mears a car rental or a cab? And how do you get a hold of them to take you to Universal?

so I don't know if anyone else has tried this but disney arranged our transport for us, we asked the concierge the day before and they arranged a shuttle, which picked up over guests too, it cost $20 for a return trip, disney gave us a phone number and told us to go to guest relations in universal an hour before we wan tot leave and they will phone and arrange the bus back. It was cheap and easy.

Mears is a shuttle bus, similar to the Magical Express buses. They will pick up and drop you off at your resort, but they will also be doing pick ups and drop offs from other resorts and parks. On our ride back from Universal we stopped at Sea World to pick people up and then dropped people off at Pop Century before our drop off at Caribbean Beach. There were several other guests from other resorts that were getting dropped off after us, as well.

This sounds a lot like Mears. I'm betting that is the service the concierge used.
