I went with one of my daughters at the beginning of April. We weren't camping, but experienced some of the highest winds I have ever known. One day the wind literally lifted our Land Cruiser off the road twice. On crossing the road from the hotel to the cafe opposite I was picked up by the wind and blown about 20 yards before I touched down. I have been in winds before where it has been impossible to stand, but I have never been blown 20 yards without touching down!
We had a couple of half days where the wind was 50+ mph - difficult to stand, but not totally mental.
You could be lucky and not experience any extreme winds, but you should at least make contingency plans.
Assuming that your tablet hasn't got a SIM. Phones use triangulation with mobile phone masts to "assist" positioning data. This can make phones give different readings to a non phone device. Also if one of your devices is able to use GLONASS satellites, that should be more accurate.
Try downloading GPS Essentials from the Play Store. Amongst a host of other things this will show you the accuracy of your current GPS reading.
The other considerations - what would you need to survive 48 hrs if your bags went astray ?? and what would you hate to loose if they were never recovered ?
On a short trip to Prague last year, I did my usual thing of just travelling with hand baggage, while the rest of the family insisted they need to put stuff in the hold. I felt very smug when it failed t turn up at Prague Luckily, it did finally appear about 12hrs later.
