Looking to plan a 7-10 day trip in Nov 2014. Important factors: family of 4 (2 teens) mix of culture (good food paramount, along with interesting architecture/museums) warm weather for at least one city, preferably with beaches potential for side trips fairly adventurous but we'd like to end up in a nice hotel at the end of the day Lima is being considered along with some place in Costa Rica. Other thoughts, experiences, recommendations? Thanks for any help!!
