Breakfast at 8am isn't compatible with 6am site starts
You're out the door before the kitchen opens, missing the meal you've already paid for. Net cost: higher than it looks.
The 'one bathroom, three guests' problem
Many B&Bs have shared bathrooms. After a long site day you don't want to wait. TNS partner properties have dedicated en-suites for most rooms.
Personal space matters on long stays
A B&B owner who loves a chat is delightful for two nights. For six weeks it's exhausting. You want a place where you can come home and decompress in private.
