We're toying with the idea of cashing in some LPs for our upcoming stay to extend one night on the Strip. The problem is our traveling companions can't get off the pot on whether or not they can swing it. My fear is I'll spend my non-refundable LPs on a room then wait so long that rooms are sold out on the date we need. I could always book another date down the road, but I'd rather not. Any thoughts or advice? I guess I could try calling the number and asking before I cash in the LPs but I'm not sure if their system will let them tell me anything of value.
