No experience with the HP version, but my wife and I used the regular Hubba Hubba to car camp a few times. (My brother and niece now have it, and use it for backpacking - they really like it. Which means I'll probably never get it back.)
Anyhow, when Karol and I used it, we really liked it. The two doors were located perfectly, along with the two vestibules. It was none too wide, but it wasn't cramped, either - and neither of us is petite. It easily holds two full-length Thermarests, side by side, with a little room to move around.
It was very easy to pitch. As far as condensation, we never had any problems - we did leave both vestibules fully open, however. All in all, a very nice tent.
After my brother and niece appropriated the tent, we replaced it with a Mutha Hubba, which has plenty of room for the two of us and is just roomy enough for us and our two granddaughters (4 and 7, feet to feet between us.)
