Hi Martin,
We went end of August/early Sept last year, the Park is no longer owned by Universal but I don't think much has changed since it did. We stayed at the El Paso (same as Terri) but we visited the Caribe which is just a few hundred yards around the corner - the parks are walkable (slightly uphill).
We had a great week there and DH mentioned at the weekend that he would like to try and catch a last minute week there this summer too - and DH never re-visits anywhere. Not sure of your group dynamics but we found the beach club a must do.
My full trip report is
here,I hope it's helpful. If you have other questions, please ask.
Have a great holiday
