In short, yes.
In depth, Trader Sam's is part of the end result of all the renovations to The Disneyland Hotel. All 3 towers were renovated (inside and outside), renamed (Fantasy, Adventure, Frontier), and a new bar + pool area replaced what used to be the Neverland Pool and Lost Bar. The overall refurb is designed as vintage Disney/Disneyland with modern touches. And speaking of removing water features, a giant waterfall/rocks area was removed for this reno as well. I had hoped to get some wedding pics around there, but I'll gladly take the current product instead.
So Trader Sam's is a relatively cozy tiki bar with Adventureland written all over it. Tastefully covered in decor, you'll notice tons of artifacts from the Jungle Cruise, Enchanted Tiki Room... Adventureland as a whole. You'll even spot some gems from Indiana Jones Adventure: Temple of the Forbidden Eye, Pirates of the Caribbean, and a certain orange bird from Florida. Let's not forget some artifacts from The Adventurers Club too. There's a well-researched collection of drinks, exclusive tiki mugs to purchase, and a good selection of underground/off-menu drinks like the Lapu Lapu, Navy Grog, and both versions of the Kungaloosh!
Some drinks, in Disney fashion, just might trigger an effect that the whole room can experience. Anything from sinking ships and volcanoes to raindrops and thunderstorms, its great. They also do a good job paying homage to the SoCal tiki bar scene. You'll notice lots of classic tiki mugs, and probably half the stuff in there was replicated or created by Kevin & Jody (Tiki Room totems, their own previous work w/Disney, etc).
