Funding slackpacking or glampacking travel is never going to be easy, otherwise everyone would be doing it!  But there are some tips that can help your slackpacking/glampacking travel funding, with less pain than you’d imagine.
I am going to make the assumption that if you’re considering slackpacking/glampacking over traditional backpacking, it may because you’re a more mature traveller, you may be a higher earner and you may own your own home.  If this is you, these tips are for you!
Saving. This is the obvious way to get together money for a trip.  But it is not the only way.  There are some other more inventive ways to fund your travelling. You probably will need some savings as cash is still, but you won’t need to rely fully on savings.
Earn money from your home. There are many options these days.  If you’re going away for a long time, you can rent out your home (or part of it) while you’re away on a regular lease.  But, if you don’t want to move out completely, you could consider renting out your home on Airbnb. Team up with a friend, cleaner or neighbour to help you do the change-overs, and you could be earning an income while you’re away. (Just remember to check your insurance will cover you!).  Very often, what you’ll earn from your home will cover more than your accommodation costs whilst abroad.
Home swap / Home Exchange:  Exchange homes with someone in a location you want to go to, to save on accommodation costs.  Accommodation costs accounts for almost half to a third of your costs while you’re travelling, so this could save more than you think!  Also, the standard of property is often higher than most travellers are used to as you get access to a whole home rather than a hotel room.

Mortgage repayment holiday. Check with your mortgage company whether they will allow you to skip a few mortgage payments without penalty.  All they do, is recalculate your payment, and you pay a little more in future to make up for the months you have missed.  Our mortgage company, for example, will allow a repayment holiday of 2 months per year.  So if we go away over the end of the year, we can take a 2 month repayment holiday in both years, i.e. 2 x 2 = 4 months’ cash flow.
Voluntary pension payments. If you voluntarily pay into a pension, you could suspend these for the period while you’re away.  But do remember to start them back up immediately after you get back!
Work. Well, working while on holiday isn’t everyone’s idea of fun.  But … if you have the job where you can work anywhere in the world, this is something you can consider. Sites like Upwork and Fiverr are great for selling your skills online. Just pack a laptop and ensure you have a good wifi connection.
Although all these above isn’t necessarily a substitution for saving for a big trip, hopefully some of these will help!
