What to Do With 3800 Hyatt Points
Your choice is to use the LCUP points that expire in 14 days. You can make a reservation up to 60 days out with LCUP points. You live in Carlsbad, CA so you have a few choices to use these points in somewhat reasonable driving distance. My number 1 destination would be Carmel. This is what I see available until mid June:
Highlands Inn

You can also use Pinon Pointe in Sedona which has a lot of availability in the next 90 days. You can get in there almost anytime.
I did not check Hyatt High Sierra in Incline Village but that too is a possibility.
You may have learned a tough lesson about LCUP points if it is impossible to use these points. You need to use your points or transfer them to II within the appropriate time period. I set up an alarm on my online calendar to remind me to do this annually.
