That's like saying, "I'm only going to punch you in the face once instead of twice, so that's a perk!" Those Universal on-site hotels are pretty damn expensive, when you compare them to numerous quality hotels in the area, many of which offer free shuttles to Universal. The advantages of staying on-site should be a real perk! But they sell this "advantage" to everyone and his cousin, so how is it still an advantage? I don't want to bash Universal, but they've been milking the early entry stuff ever since the first WWOHP opened. They continued to do so long after the wait times became reasonable (and you can breeze into FP through the single rider line). Not worth it, IMHO.
I have to agree with you on this one. They added all of the other hotels to EE which makes it somewhat useless. It is even worse at WDW as we started avoiding the EE parks many years ago.
As for EP access...it makes it totally worth staying on-site. Disney's new FP+ system is ridiculous...I'll take unlimited front of the line all day long...even if I don't get it for FJ and the Gringott's ride.
