YES!!!!!!
Went to both this May, stayed offsite for Disney and stayed at the Portofino for two nights for front of the line access. (Wish the new one was open then---what a great rate!!!!!!) The new hotel is supposed to have the boat access, and that worked just great having these boats take you the front of both parks.
We loved every minute of WDW and Universal/IOA, but I almost did not schedule more than a day, and then we were just going to Universal. Saw the promo video for Universal and we were hooked.
My 5 year old and 10 year old had so much fun at these two parks, that we spent 3 days at Universal, and 4 days at WDW parks, and it worked perfect for us. We rode everything, and most of it many, many times.(We got away with just doing a few hours at EPCOT because my kids thought it was a real yawn).
We left our hotel real early in the AM, and left our luggage at the front desk at the Portofino, and even though we were not checked in yet, we got a temporary room key for front of the line. We only stayed two nights, but used front of the line for 3 days.
