I did that last year spending about RM12K traveling around South Island, New Zealand for 12 days. Did a lot of extreme stuff like skydiving, bungy jumping, Nevis swing. Also spent some time doing sight seeing, chilling around from town to town. I did that with 7 buddies and 1 of my buddy's mom. It's so far the best trip of my life. I'm only a mid income earner but no regrets at all with the experience that I gained throughout that 12 days. Just got to do it with the right travel buddies
