I'm toying with the idea of visiting Vegas during Christmas this year. After go ogling the weather in December most sites said it's roughly mid to upper 50's that time of year. Can you even go swimming at any of the hotels this time of year in Vegas? I was looking to go somewhere warmer during the holidays and while that's warmer than where I'm from (the mid west we usually visit my brother's family in Oregon but it's too gloomy for my liking around Christmas and not a lot warmer either) feel like I might not get the sun/warmth I'm looking for.
