My family will be at Vero Beach in a 2 bedroom villa on December 30 and 31. My children will be 12, 12, 11, 8 and 6. My questions are : Will it be warm enough in the daytime to use the pool? What type of activities are available for the kids at that time of year? Is there a special activity or party for New Year's eve ? etc. Thank You. Lori
