I'm actually in the process of doing just that. 325K miles left to allocate, theoretically tonight.
Already booked flights to PPT, JRO, and MLE, that I actually planned out real trips around over the last couple of days, prior to hitting the 'buy' button.
I'm trying to decide & nail down between the rest of my "drafts" before purchasing. At least get them a bit closer than the tentative SWAG state they are currently in, just in case. Which feels somewhat like throwing darts at a moving covid map while blindfolded. 😁
