I’m planning on staying in Baan Dinso Guesthouse in Bangkok for 5 Nights. And then a day and a half in Kanchanaburi (Blue Star Hotel), 4 nights in the Tri Gong Residence in Chiang Mai. I believe I’m going to Koh Phangan for 4 days, probably at Harmony Beach Resort and then on to Koh Phi Phi for 5 days. However, I’m having difficulties deciding on where to stay in Koh Phi Phi. I’m thinking Phi Phi Hotel. I don’t want to spend more than $50 a night. Does anyone have any other suggestions? Does anyone have first hand experience at any of those establishments I’ve mentioned? Also, How necessary is having AC in the places I’m staying? Is the extra money it costs worth it? I’d be coming from Northern California in the middle of winter (pretty cold), so if its over 85 F at night I’ll probably want AC. Does it stay that hot or does it cool down at night? I’m planning the trip to be about 3 weeks and planning on saving $1500 (excluding the plane ticket). Is this sufficient?
