We are heading for our first trip tomorrow (Thursday) and I was also surprised to see that no more rooms are available. I'm super glad that we booked the Portofino. I wonder if it is so booked because of the "Annual Passholder's Night" on Sunday night? US closes at 8, and I'm wondering if it would be better to head to Volcano Bay that afternoon, and spend the evening there. We had been planning on Monday morning, but wondering if all the passholders will get up, tired, and decide that Volcano Bay is just the place to hang out Monday morning. Any advice on that?
