Let me share a story...
I visited Universal during the last week of December. I was in line for Guest Services and I was behind a group of five adults. They bought Universal Express Plus tickets for their group. The total for two days of Universal Express Plus tickets was around $500!
Compare the cost of their Universal Express Plus tickets to a Universal Orlando onsite hotel. The Royal Pacific Resort rate for that time period was around $299. I believe $299 is the rack rate for the Royal Pacific Resort. With the extra three adults, they would have been charged an additional $25. Their hotel stay for one night would have been $375 (not including tax or sundries costs). The hotel bill may be pricey, but consider that if you stay for one night at an onsite resort, you can use your room key for two days. You can check in as early as 7:00 am on your arrival date and use your room key up to midnight on your departure date.
Thus, if the five adults read the DISBoards and booked an onsite hotel, they could have checked in at 7:00 am, left their bags at the bellhop, and had fun with their room keys at the parks. If the group stayed onsite instead of buying the Universal Express Plus tickets, they could have actually saved $125! Their Universal Express Plus tickets did not include a hotel stay. The Motel 6 near Universal was running about $50 during that same time period.
Golly, I sound like a Universal Orlando onsite resort salesperson! Maybe I need to fax my resume to Human Resources!
