You can reserve all three BUT you will need an AP holder registered in each room when you check in.
That is the official policy.
You can always call Loews. Loews (the hotels) and Universal are two totally separate companies. I would call Loews and see if you can get the same rate for the other two rooms even if you are the only AP holder. The worst they can say is no.
Have you considered a suite? You would need only 1 AP holder. Sometimes a suite with 2 bedrooms is about the same as 3 rooms. There are multiple bathrooms In most suites.
I'll be the only AP holder in our group. I'll try calling Loews as suggested to see about an exception. As for a suite, it won't work for this trip. Thanks everyone.
