My experience travelling with kids heavily favours hotels, TBH. Especially brands hotels. They're generally:

  - secure,
  - clean,
  - *fire-safe*,
  - always have my rooms ready,
  - have working WiFi,
  - don't have things like unsecured bottles of bleach in bathrooms,
  - don't have stray dogs hanging around,
  - don't have inappropriate art, books, TV-stations, etc.

Admittedly I'm less price-sensitive than some, but I also don't find hotels massively more expensive.
