We are a family of 7 with 5 daughters (NB to 8y), from abroad. We plan on a 9 day track with an RV during February, starting and finishing at Las Vegas. We would like to see Zion (incl some short walking trails) and maybe Bryce too (weather trouble?), and get to see Sea World in San Diego (for the kids.)
* a recommended rout for the above plan?
* any suggestion of a completely different track around Las Vegas at this season, including mainly nature (Lake Powell?) but also kids attractions ?
* would it be possible to also include Death valley or Joshua tree ?
* where would winterizing be mandatory at this time of the year and will just emptying the water & opening valves suffice ?
