I'll second that. CM is a nice city with some interesting things to see and day trip possibilities. But I think 3 days is a good amount of time to see LP and the surrounding sights. But I don't know if the season effects things too much with regard to places to see. I was there in November which was great. Not too hot, rainy season over. LP is very photogenic and filled with temples large and small. If the Kuang Sii waterfall is accessible it is quite nice and worth a visit.
