Not if you do it right. I was on a super low budget for that trip. Few things I would recommend to watch your $$$.

1) Stop at Megamart in Mobay a Collapsible cooler (or bring with you from home). BUy your own bottles of liquor/beer/water/ect and just make a run to store for ice when needed.

2) Try to find the local spots to eat and you will spend a lot less and eat a lot better.

3) Pattys and roadside jerk chicken box meals. Yep

It is possible....and deBest part is....instead of spending all that time sitting in the same restaurant at Samsara, you will be out there experiencing more of Jamrock. Fun stuff
