Which Spa suite do you ladies prefer? The Tower Suite at TI, or the Executive Resort Suite at Horseshoe?

Both are good. You should be fine with either

The tower suite at TI it has a big jacuzzi tub with a mirror right in front of the tub. If you are someone who likes to have some naughty fun with your provider in a tub it is perfect. Plus that room has two bathrooms.
The Horseshoe (old Bally's hotel) tub has no jets and it is in the room and the bathroom has no privacy except for where the toilet is.
Have fun here in Vegas xo
