I had no problems with this tent at all in high winds and rain, and as the doors go that gave me no problems as well, just peg them down no rain entered into the tent.
As for the condensation issues in the tent you really have to pull the front guyline tight and that streaches the tent so it's nice and tought, then the condensation runs down the sides of the tent rather than sit in the middle and drip on you.
You can also buy some heavy duty velcro strips £5 to stick the bottom of the doors together get the proper brand and they stick fine. I recommend a towel though on the outside flap as this stops the draft and bugs entering.
I found the inner bedroom sloping side to be fine, just make sure you peg it down tight and the water runs down with no sagging of the material.
No mesh in the doors is a problem and it only really sleeps 3, (try getting 2 people in each sleeping pod with airbeds in the sleeping area, not much fun) will take another reviews advice and get some mesh cut for the size of the door and stick it to the tent with the branded velcro that works.
But very happy with this tent becouse i got it in a great deal, so i can put up with the absence of mesh.
Dont waste money on the sun canopy we tried it and dont rate it, you have to concider how much you would then be spending on the tent when you could go for another tent with a front zipped up porch provided anyway, (unless the canopy is a great price).
Hope this helps all those owners of a coastline deluxe and would be buyers.
Recommended but only if you get a good deal on it.
