I am planning a visit with my wife to Khao Yai park for 3-7 days in Feb. 2008. Though I am 62 and my wife 60, we are great nature lovers and also like hiking and trekking of moderate difficulty. We have doubts about the optimal choice of lodging (inside the park or outside). On the one hand, we would like to waste the minimum of time on the way from the lodging to the hiking trails and back; this tips the scale in favor of interior lodging. On the other hand, this might entail great expenses of renting a van for the whole stay (does this also imply hiring a driver?). Neither would we like to rely on hitching. Can anybody with experience in the park give a good advice?
