Nice place, hope you have a good time!
Which one of the DD hammock are you thinking of? Different hammocks have different design philosophies behind them and then it also depends on the size, fabrics used and amount of neat features you’re getting - plus of course production costs and how much they think they can charge (brand tax and all that).
The DD Frontline XL is for instance narrower and less roomy than the HH Explorer Deluxe, but has a double bottom so you can put a thin sleeping mat in for insulation. Both have built in mozzy net and heavy but easy to use suspension systems. And so on.
A lot of it depends on how you sleep and what you find comfortable. I My DH is comfy in his Frontline XL but as a side sleeper I am not, whereas I can always find a comfortable position in my Explorer deluxe.
Another consideration is weight and bulk - sometimes your perfect hammock for sleeping in is just too heavy or big to be useful.
I am impressed by the DD hammocks that I/we have, so if you find one you like, I don’t see a reason to buy anything more expensive for the sake of it.
