You are better staying just off the 192 in Kissimmee.
Within easy reach restaurants, supermarkets plus good access to Disney and the I4.
The main 2 areas are Formosa Gardens and Poinciana Boulevard.
FG, has Formosa Gardens, Rolling Hills, Windsor Palms and Indian Creek plus others.
We have stayed at IC before and could recommend as there is a good choice of 3,4,5 bedroom homes.
Whilst we have driven round the remainder a lot of the properties seem to be 5,6,7 bedrooms particularly at FG/RH. WP is probably the nicest but have not stayed there yet.
Poinciana is a few miles up the road and further away from Disney/I4 - developments such as Indian Point, Eagle Point and Cumbrian Lakes (where we are staying in August) - plus others too.
PB is quite a long road just off the 192 and is probably a good 15 minutes further away from FG, and because of that further away from the attractions too.
Would recommend Indian Creek or Cumbrian Lakes, really though you want a home less than 5 years old and preferably a south facing pool , one that is fully fenced for exta privacy.
