I am no longer seeing this booking option. Formerly, I would use code 51440 to find it, but that code seems to behave differently than in the past. Has the hotel discontinued the booking option? Has Hyatt deprecated code 51440? If so, is there a new code to get similar results? (For that matter, are there other useful codes that might return good rates at HH Jersey City or other hotels?) Thanks for any insight.

Edit to answer the question "Has the hotel discontinued the booking option?" (I'm still hoping for answers to other questions.)
The new interface (does anyone like it?) confused me. To find the Lp Suite Pts Upgr from the booking page, click on Suites, click Use Points, and click on Select & Book. There, wasn't that simple?
