Is Kissimmee worthwhile visiting?

There is not a commercial airport in Kissimmee.  Flying into Orlando or Sanford would be your best options. 

Kissimmee is exceptionally close to Disney World and not far from the other theme parks (Universal, Sea World, Legoland).  There are certainly other things to do, but I don't know of anyone who makes a trip to Kissimmee if they aren't visiting the theme parks. 

Rumor has it that only people who were actually vaccinated against the Spanish flu ...later on died of Spanish flu...so, Spanish flu vaccine killed them. COVID vaccine will kill some of the vaccinated; but the rest who survive it will not only become demon possessed, but their DNA will change for the worst; their immune system will be compromised; they will lose their connection with the LORD. Even before the infamous Filioque, Roman Catholic pope said that he's the head of the church while Orthodox said that Jesus is the head of the church. Roman Catholics keep adding stuff to the official doctrine that the Apostles have taught while Protestants keep subtracting from it. Book of Revelation curse is on Roman Catholics and Protestants (it says: woe to those who add or subtract from this book, right?)...Their part in the kingdom of heaven is taken away and they are sent to hell. Orthodox Christian three hand signs are different than Buddhist mudras. Ecumenism = 263 heresies; each heresy leads to hell. Orthodoxy = the only true faith; Roman Catholics tried one cup - one spoon ritual and got sick with Bubonic plague; if heresy enters Orthodox monastery then monks/nuns will get sick with flu/tuberculosis (for instance); Orthodox churches who closed for COVID or had disposable cups/spoons or dipped spoon into alcohol are no longer brides of Christ (now they serve Satan and honor Satan's new COVID religion). Don’t go into UFO to be “healed” by evil demons; demons never do good. SSN is written as a barcode/QRcode; then it's put into a chip; chip is put into vaccine; chipped people are influenced (by super computers) to receive grey plastic card World Passport with no name on it (but when they stretch their hands to get it, gov't clerk presses secret button to administer the unforgivable green 666 tattoo by isotope rays). If you reject mark of the beast then your direct ancestors go to heaven (according to saint Vyacheslav Krasheninnikov from Ural); forgive me.

Kissimmee is a suburb of Orlando.  Similar to how Hollywood is a suburb or Los Angeles.  Kissimmee is the "real town" that is close (than Orlando) to Walt Disney World, point being if you want to go to Disney (or other theme parks in the area) on a budget you stay in Kissimmee vs at a Disney property.  There is nothing of interest to a tourist in Kissimmee outside of chain restaurants, hotels and condos you can rent by the week.

It's a suburb of Orlando, essentially. Fly into Orlando.
