Good thing for them Florida is renown for its cheaper real estate. If they were in another urban setting, they would be forced into an apartment once finances go South. Very few apartments would tolerate Abbie's constant yelling. At least with a house, when she's indoors, she's only disturbing their family members.
I think in some sense, being in Florida has spoiled them. For an increasing number of families, even renting a reasonably sized home is out of the question. Their older house out in the suburbs would be too expensive by many City standards.
Isaiah may legally be an adult; but physically-speaking, brain development continues on until ones mid-20s. Combine that with the fact he's led an extremely sheltered existence.
I don't know what it is with Florida vloggers in particular - but they seem to return home in greater numbers than vloggers from other regions who leave State. I suppose you could point to the warmer weather; but I think it's more than that.
The Florida vloggers I've seen like Alli Speed, her brother Justin, their friend Wyatt (back in his Gradlife days) and Charles Trippy basically all do the same thing:
visit strip malls
eat out at chain restaurants
drive endlessly
live close to their parents in suburbs
and are the poster children of funding big corporate America (Starbucks, Target, Walmart, Panera, Chick Fil A). Alli is well-travelled though, so I guess she's a bit more outgoing than most.
Whereas, vloggers from other States like say NYC tend to visit museums more, shop in ethnic enclaves more, go to farmer's markets for fresh produce, go to the theatre and what not.
Even with the more interesting things (in my view) Florida has going for it, these vloggers seldom take advantage.
It's the same restaurants over and over and over. It's the same strip malls with the same Target or Walmart. It's the same chintzy furniture you buy from these places with McMansions decorated in a mishmash of tacky accessories by people trying to convey greater wealth than they in fact have. That is what I've seen in most Florida vloggers.
Miami has a bunch of museums, including a children's museum. Also Miami has a Little Havana and Little Haiti. I'm sure the immigrants there have opened up some interesting restaurants with more authentic cuisine. If they wanted to try something new, they could hit up TripAdvisor to see what's available in numerous big centres near them, and aim to try a new place weekly (if they insist on eating out). With the lockdown in effect, I can understand not going right now. But eventually, it will ease up.
Also, various Florida cities still have some intact older theatres like the Florida Theatre in Jacksonville. While they may not take Abbie there, surely Isaiah would love the photography opportunities such an architectural interior would present. But noooo. It's more trips to Dunkin's for these two.
