we are planning a 7 day trip leaving San Diego on 14th August-yes, just over 2 weeks away- with 3 young kids. Just want to see some desert landscapes and classic western towns with maybe one night at G.C. and one night Las Vegas. Back to San Diego on 21st or 22nd. It will obviously be pretty hot so sightseeing from airconditioned car and arriving at motels with a pool and a tv to watch olympics might be all we manage. maybe-Joshua Tree, Sedona, G.C., Las vegas?. Would love suggestions of a route and places to stay, anything we really must see, or interesting for kids. Also we havn't booked accommodation- any suggestions especially at G. C. -I guess we are late now- do we need to book all our accommodation now or just roll up? Thanks very much for any suggestions.
