I stayed at Trailer Ranch for two months a few years ago. The smaller sites on the left as you enter seem a bit cramped, but the big rig sites on the right side are quite nice. Lots of shade in the park, which is nice in the summertime. And much closer to the plaza area than many other parks.
Would I stay again. Sort of. As a tourist, yes, no doubt about it. But I have little interest in spending two months receiving radiation at the hospital on a daily basis again, so no, I'm not wild about doing that again. (Though the Cancer Center at Christus St. Vincent Hospital is indeed first rate.)
