On the Wonder, back in 2014, at Signals (Quiet cove bar) they had Devil's Triangle IPA (Florida Beer Company) on tap, Cigar City's Jai alai in cans, and several different Kona Brewing products in bottles - Longboard and Bigwave were on tap, bottles of Castaway (IPA) and a Porter whose name I cannot remember. Nowhere else on the boat could I get any of them, and nobody knew what I was talking about when I asked. Devils Triangle wasn't a beer I'd go out of my way to get again, but for an IPA on tap on a big boat in the ocean, it was pretty nice.
We've been on 3 cruises since, and haven't seen a single IPA on tap anywhere, and only come across bottles of Kona's Castaway IPA (missed opportunity for
DCL there...) on one other cruise, also at Signal's, but this time on the Magic. So we either got really lucky in 2014, or they just drastically reduced their craft beer selection sometime after that, or both. I've heard Loose Cannon from Heavy Seas is sometimes on-board but we haven't seen it yet.
If I could get a get IPA on tap, and 1-2 other options in bottles or cans, I wouldn't need, or want, to bring my own beer on board. But to only have "big beer" products, and all be pilsners or adjuct beers is a really poor selection.
Last cruise I got on the FE group, to try and get others to participate in a beer exchange. Bring a 12oz craft beer from a local brewery near your home, and we can meet and exchange. Sadly, all I heard was crickets. I'd love to get 5-6 other people and trade some beers and try stuff I cannot get in my area.
A side question, last cruise I saw someone walk on with a pack of "Corona Light"... WHAT is in those cans???? Colored water? haha.
