Personally, this region is perfect for a day trip but if you plan to stay then there are options like Hintere Wasserfallen , Obere Wechten mountain guesthouse or other options that you could find right .
The train tickets from Basel SBB to Liestal is round about 7 CHF one way (children below 6 go free), the TNW day pass is the most practical option when planning this trip. The ride on the gondola is not included in the TNW pass or the half fare card, expect to spend 17 CHF for adults and 10.20 CHF for children between 6 and 16 years.
The scooter rent one way is 12 CHF for adults and 7.20 CHF for children. A usual meal in Switzerland is around 40 CHF per person and your stay will depend upon the type of hotel you choose.
Lastly, this is a trip worth doing - it is never too crowded, and it is perfect to experience the beauty and essence of Switzerland in a very short time! I wish you an exciting scooter ride down the hill!
