Murena.com works fine for me as an alternative to Google / Proton

Based on their specs the twingo will do 130 and the spring 125 km/h . Both fine for shorter trips to the next city or so.

As others pointed out herbs might be the only thing that come close to being cheaper. Speaking oft herbs - Weed might be the only thing that fits your requirements thats actually cheaper this way.

You can still use booking. You just don’t need to do the booking via booking. Most Hotels have their own Homepage. Just book from them. It’s cheaper anyway. For Airbnb I see no real alternative. You might search for camping places via your preffered map app. They are often not listed on either platform.

Omg that song is awesome. Thank you for the recommendation!
