There are 2. One regular and one overhead. They are not designed to both go at the same time although as you switch between the 2 they both will be on but at lower pressures. Be aware that the overhead does drip if you've used it and switch to the other.....cold drops of water. Sometimes it drips even if you haven't used it.
Why can't they fix the drip from the rain showerhead? I hated the freezing cold drips while showering. So I rigged up a towel to contain the drips, at least for a short shower until the towel got soaked through.
I think they have the overhead in VGF and maybe VGC, aND I don't remember them dripping water like BLT does. I don't know what they did differently in the resorts. But I'm with the other posters - that's some cold drops hitting.
