my husband and i will be flying into vegas sat. jan. 31. got cheap fares - we don't really care about vegas. will arrive midday. he loves the desert. we have a daughter in la to visit. is it possible to drive to death valley the first day and have enough time to explore a little? he has suggested we next visit sequoia, although i am unsure about this trip in winter. is is feasible? (it is just a thought, and not necessary if the conditions are questionable this time of year). then on to la for a couple of days' visit. then perhaps to joshua tree for a day? then the grand canyon? then lake mead/hoover dam and a night in vegas before our return flight saturday feb. 7? is this doable? i have little info about the weather this time of year, and this trip has come up so last minute that i feel a bit shaky about it. any insight anyone? i love this site! thanks for any help you can give.
