I totally understand your situation, sometimes during travel, after a long tiring we just wanted to rest, that's the reason I have never stayed in dorms. Don't feel bad that you have to change the place, I am sure they will understand. Sometimes in internet people will judge you are not a true tavelers , can't adapt with the place u travel but it's your money and you can do whatever you want and however ways you travel and happy .Glad u decided to change the place, because the new place is so stunning!
