HI!
I did Outback Safari and it was the best!! Me and my family enjoyed it very much. Guides are very cool, Macao's beach's terrific and the experience is amazing. I'm sure you will like it.
I've heard good things about B?varo Runners, and food's good too, but it is not as funny as Outback. If Rigo is your guide, then you'll have more fun if possible.
they both cost 75U$ (if not, they are 80U$, but no more).
Ask for Linda or Nicola from First Choice (or maybe Signature?) at Sirenis Hotel, and they will show you all the tours and will give you the prices and everything.
Hope you will enjoy there!!
