My wife and I have about 500,000 left, have spent 1.5 million, transfers to Hilton, Marriott, Distancia, a few flights to Cental and South America, and even two KLM business class tickets to Kenya from LA, but that was a long time ago.
Word of warning about Distancia transfers, they are only good for three years and all miles expire. Only way to extend miles is to take a paid flight on Distancia member airline (TACA etc.) Hotel stays car rentals do not extend miles in Distancia like LP. Paid flight only extends miles for one calender year. If you have miles expireing this year you are able to use for ticket next year but you must pick up ticket before end of this calender year. Good news Distancia still allows accounts to be combined for a ticket.
