I can only dream of a solo trip.
No consulting anybody else for every single decision.
No having to round people up.
If I am hungry or just see something I would like to try, again no consulting anybody. No what are you getting. Well lets get this and that and we can share. No discussion on if the dining plan is WORTH it.
See something you want to stop and watch for a few min? Do it. Want to stay half an hour, no problem. There is no one standing off to the side tapping their foot.
You are not dragged into stores you have no interest in.
Bathroom breaks at your leisure.
Like I said, I can only dream.
And about the high end hotel room, if you would only be considering it for the express pass, you might want to check out what it is running as a stand alone on the dates you will be there.
With 2+ people it is always a good deal, solo it may or may not be.
