I would 100% suggest the Uber app / car service. We stayed at Universal (Royal Pacific) in late September, and used them to/from the airport. Each time, we waited less then 5 minutes for the pick-up and had two great drivers and very clean cars. Cost was only $35 each way, no tip needed. Even better, if you have not used Uber before you get a $30 credit on your first ride. We were able to use it one-way, since we had two people who each had an Uber account. Talked to one of the conceirge's at Royal Pacific, he said they are seeing Uber take over more and more every week with the number of pick-ups and drop-offs. Happy to provide the referral link if you would like.
