I did this excursion a few years ago. Yes, there is a tram. You check-in at the excursion hut near the entrance and then wait for the tram to take you to the "ranch" at the far end of the island. I'm 98% positive there were platforms because I am also short and I don't remember having a problem getting on or off the horse. Once you get off the tram they will have you wait under a hut w/cool drinks available until they get the horses together and start matching rider and horse. I tipped one of the staff and had him take pictures since I was alone on the excursion. He did an excellent job and I didn't really need to buy the Carnival portrait they take (I had read the photographer isn't always there) even though I purchased it anyway. I try and do trail rides whenever I travel and this was the BEST one I've ever experienced.
