Just throwing out some purely anecdotal thoughts-- I've got friends, coworkers, and family that live in the North East (Armonk/Ballston Spa/Saratoga Springs/The City, NY; Saddlebrook, NJ; Providence, RI; New London/Groton/Mystic, CT) most of whom love to travel and enjoy going to various places, including Las Vegas and Florida (for Disney as well as Miami and various beaches).
What I've heard is that they're itching to go places (other than things a local drive away), BUT that the main hold up is how uncomfortable the trip would be vs the cost: masks on a plane, masks at theme parks, no shows (Vegas), limited things being open, etc; and less so about any quarantine implications. The one exception to that is Hawaii-- I've heard a couple of people say that they'd deal with the unhappy flight to go there, but don't want to deal with the strict quarantine they'd be put through on arriving (stuck at hotel with a one time use key to get you into your room, regular checkups from police, and arrests, fines, and deportation if you break quarantine -- Hawaii really doesn't want visitors to come).
Not saying that quarantines don't have impact, just in the circles of people I know it's not that big of a concern- whether that means they'd ignore the restriction or because they work from home so it's not a huge problem.
