Cleburne State Park
Haven't done reviews on Whitney SP or Meridian SP. Whitney is nice but I prefer Meridian. Also, have you thought about McCown Valley Park on Whitney (Corps Park)? I think it's much nicer then the State Park and that takes a good bit to get me to say that. Working on a review for McCown and hope to have it up by the end of this week.
Took a look at Fairfield and did not like it. Many do but it's just not for me and DW.
Can't say anything about the others you asked about. Will add a big "Thumbs Up!" on Tyler SP. Have been there twice and really enjoyed both trips. Hoping to return soon and do a solid review on that park. Only thing I'd warn you about is to watch out for the racoons in this park. They are VERY bold and have developed quite a taste for "people food". They won't hurt you but, given a chance, they'll snatch a loaf of bread before you can bat an eye

! Cute but you can find your self making an unscheduled run to the store.
Hope this helps and feel free to e-mail if I can be of any other help. Until then,
Happy Camping!
