You might look into a wall tent. 14x16 would work great for a family of 5 lots of space and it can be heated by a stove or heater in colder times of the year. I have a 16x20 which has been great for family trips and glamping with my fiancée. I bought mine from wall tent shop i did shop around a bit and found them to have the best price and most helpful staff that did a great job of answering my questions and picking the best tent for my needs. they also have a great layaway program that was easy to set up and make payments on, this was a great relief because some wall tent packages can seem very expensive but when you look at it in the long run a well maintained wall tent will last any where from 15 to 25 years in some cases even 30 years, where as a tent from tristate or Walmart will last maybe 5 years and cost any where from 3 to 5 hundred dollars depending on size.
