I'd look at Vegas, but not Elara or Trump. Flamingo doesn't have ROFR, LV on the Boulevard has lowest fees, but likely higher buy-in due to ROFR propping up prices.
Points are points. I went with the LV on the Boulevard property because the MFs are low and will likely stay that way for awhile as it remains in sales with a developer subsidy.
One note on the 12 month booking advantage is that it only works for your season and unit size for the full Saturday to Saturday week. If you want 5 days, or a 3 bedroom, or some other change, you are looking at 9 months out just like the rest of us. Might as well save money and enjoy flexibility.
I've been to both Sea World and Tuscany and, while I like them both, I prefer Tuscany. Never had a problem getting the unit size and dates I wanted at either. Just plan in advance. Attached is a screenshot of Tuscany 9 months out, showing 100% availability in every room type, including Spring Break dates.
