Alas, we have only a half day/full day/half day in TDP, but still want to experience the park to the degree we can. There is a myriad of online advice about hard-core trekking (the W and such) that deal with multi-day hikes. Is it possible to see some of the major trails in a day or half day? We'll be staying at a hotel on the park grounds or just outside it on night 1 and night 2, and will have a rental car. Advice?
