we've done this room with 4 adults and 2 kids 4 times with no issues; however, we actually will be doing it with 4 adults and 2 teens in about 10 days. we shall see if it still works out lol. my 15yo is basically an adult at 6'2". although we are used to traveling together and sharing bathrooms which is why it works for us, and my parents are the only ones we could ever do this with. i think knowing how you travel together is a bigger factor then size/how many adults, etc Because we couldn't do this same configuration with my inlaws, BIL/Sil, friends etc
