ramble, every tiki bar needs ramble if you ask me.
As in "Pirates are not tiki" "well they can be" stuff like that, debate is not a bad thing.
Don't know when a difference of opinion became so offensive or frowned on.
But more to your question, would guess you have seen this...

"I'm hoping someone has some fresh awesome ideas that I haven't come up with yet!"
I say look more to the old ideas like the decks and landscapes of Frank Lloyd wright.
Type in mid century modern patio online and look at the pics that they show for that.
See here....

For outside I say HUGE rocks in the deck.
They don't cost a lot but the hauling and placement may cost a bit.
Plus rocks don't need watering or feeding they don't die and always look great and
can be seating or a place to put your drink.
Wish I had put way more huge rocks in my deck.
Tiki is all about natural, wood, rope and bamboo, maybe a pond ect...
Outdoor tiki should be a natural wonderland as if Robinson Crusoe or Gilligan built it with stuff left from the boat.
This is grungy tiki or you could say old school.
Pretty tiki is altogether different, Don't fire me but pretty tiki is not really a style I like and not a fantasy land like old school tiki.
