Can anyone suggest, from experience, the best countries to visit with JY in February/March please?

I've been to Cambodia, Vietnam, Borneo, Canada and Myanmar and I'll be going to South Africa soon. I'd like to go somewhere warm, but don't really fancy India as there's such a lot of travelling most days. Australia and New Zealand are just too far.

What tours have you done at that time of year that you can recommend? 

Thank you

Rose
