6 days tour from Kunming/Lijiang/Kunming by train.

We have 5 nights 6 days and plan to travel from Kunming to Lijiang and back to Kunming to catch our evening flight back. Is it possible to cover all these places by bus or train? Taking bus or train (morning or night will do) is faster and more convenient? Any recommended budget hotel (USD45-USD55) in Kunming city centre with steet food and shopping malls nearby? Thanks.
