My wife and I stayed at the Hard Rock for my birthday and my gift was a new tattoo. I was able to coordinate, get a quote and book via email--which was helpful.
The shop is tiny (personally, I think there's entirely too much apparel for sale, but it's not my empire so that's up to mister Hart) so I wouldn't plan on rolling in with six of your friends to watch you get work done.
It's also probably 20-30% more expensive than your average shop in the area, but that's not unexpected given the location/owner/chain etc. Just don't be surprised when you want to drop in, get a quick cross/love-into-an-eternity-symbol/bird silhouette and you're quoted 150-ish bucks. Manage your expectations.
Shop is clean. Staff is as friendly as you can expect from a tattoo shop and the work done is great.
