Welcome to queensland guys!! It's huge place! Sorry you found our natural environment not too exciting!
2km of walking in total is not a lot as for your fatigue perhaps this is not the tour for you if you're a little older as paths are not designed for the elderly and we agree it's a long day! A total of 350 km driving and approx 9 hours in total with our beautiful customers :)
This tour is designed so people can see as much as possible in the one day, it is not a tour designed for giving knowledge purely sightseeing and never gives the impression that it is a fully narrated tour in every moment of the tour. Good luck on your future travels :)
As for value for money an Uber will cost you $400 return to Mt Tamborine. Even more to Springbrook.
Perhaps you might rent a car?
$100 + $75 fuel + lunch + 40 + drinks ???
Customers still not value for money?
Your lunch is $40, not to mention your snack and water. Viator takes 30% any cheaper and we would be working for free :(
Future Customers - if you want to see Springbrook and Tamborine 1.5 hours to Springbrook 1 hour to Tamborine, no helicopters available so it does take some time!
