Tuffgong...many people tour Appletons and continue on to YS Falls and/or Pelican Bar...sometimes Mayfield Falls etc.
I'm barely a rum drinker...one or two every few months or so...but I LOVED touring the rum factory...I found it very interesting and since you're a rum drinker, I would think you might enjoy it even more than I had.
I can't tell you how the "new" Appleton Rum factory is doing, but I would hope it's even better than the earlier years when I had visited.
