The temperature is not bad, especially towards the end of the month. The average high on April 1 is in the lower 60s, but by the last week of the month, it is in the lower 70s. The biggest problem will be rain, since it is one of our wettest months. That can lead to wash-outs along the trail and, occasionally, flooding. The Park is pretty good about repairing the trail in the warmer months.
As for hotels, it all depends on the town and day of the week. The ones in the St. Charles Historic District and in Hermann tend to fill up on the weekends, quickly. Still, you should be able to find one in St. Charles, although it might be a mile or two from the trail. I've not been to Hermann in April, but my guess is it probably doesn't get too busy until after school lets out in May. Sunday through Thursday is usually not a problem for any town. I think you will have no trouble getting a room in Clinton, Sedalia, Boonville, Jeff City, or Washington.
