Yes, and that is true with well-designed dual-shower head setups. Unfortunately Marriott's particular implementation has the wand blocked by the rainfall showerhead. You can raise up the showerhead to the top, but the flow of water.. just hits the back of the regular showerhead. So if you want to use the wand, the end of the wand is even lower than the lowest part of the rainshower head (which is angled). When I do this, the water basically hits my stomach.

The only way to get a decent shower (as I indicated above) is to physically unscrew the showerhead - which is leak-protected with teflon tape and removing it strips this teflon tape and creates leaks - so you can raise the wand to the top without it being blocked by the rainshower head.

edit: just to make this concrete, here is a picture of the AC Beltfast shower head. Notice that the rainfall shower head is far enough away from the wand that you can position the wand all the way to the top. Compare that to this where you will notice that the rainfall showerhead is too close to the wall and, therefore, raising the wand to the top hits the back of the regular shower head. In addition, unlike most wands - which have good "spread" (like the AC Belfast picture) - the Marriott wand has a very tiny spread. So even when using this, you don't get good water coverage.
