It doesn't take long to see the blooming desert. It will depend how long you 0lan to hike.There are many campgrounds but don't know about hotels
The flowers are concentrated in half a dozen small areas so you can see them in a day but the park has a lot of other features and wild life that are worth investigating. A good 4wd will open up more to see and of course exploring by foot takes even longer. It is a big park with lots to see depending on your interest. Lots of trailer and motor homes parked on BLM land very near the visitor center which I believe is free.
A day or two should be fine, but it really depends on how much hiking you want to do.
Only one day, two max.
