if you are a loews gold or platinum member, mention that when you book your ressie for the free upgrade to a pool view.
if you are not a member, go to loewshotels.com and apply for the card.
you will start out with a loews blue card. read thru that site for the background and perks for each color level.
once you file for the card, and if you have already booked your room, call the hotel direct and let them be aware you are a loews member and ask if they will upgrade you for free.
Christmas time? i have no idea, i never venture outside of my house on the major holidays.
