I backpack solo, and hope to start backpacking with one kid (age 6) and sometimes the entire family (wife + 4 kids, ages 6 months to 6 years). We'd mostly be going on trips in the mountains of West Virginia with 2-4 miles of hiking per day with a 3 night maximum. (Dad can only carry so much diapers and baby food!) I would also ideally like to use one of the tents by myself for camping in all seasons, including winter with heavy snow accumulations in the mountains. I currently only have an 8×10 silnylon tarp which I'll continue to use when solo and I don't need something heavier.
I'm thinking of getting two Golite Shangri-la 3 tents. Rather than get the nest (bug net/floor inner tent), I might get just the floor and sew in my own bug netting perimiter and door. This will put the weight of each 3 person shelter at about 3.5 lbs for a total of 7 lbs. A few other factors are the teepee shape appeal to both me and the kids, and the silnylon Golite uses is PU-coated on one side to help prevent silnylon misting.
What are your thoughts on this? Bad idea? Better options? Tried the Shangri-la 3 and did or didn't like it?
The main problem I see with this is condensation, and the kids will probably get their bags wet from inevitably touching the wet walls. I'll of course pitch the fly high enough for decent ventilation, but I'm sure condensation will happen in this humid summer environment.
I'm also a little unsure about how well the Shangri-la fly will keep out spindrift compared with a double wall tent, but it seems to be used successfully by many in winter.
