At DSV1 and 2 they took out the jetted tubs perhaps 8 years ago because they were a housekeeping nightmare. But IIRC they both replaced the jetted tubs with soaker tubs. And both (in the master BR) have a nice sized walk-in shower. The lock-off (smaller) side has a tub and shower curtain. Since you hate the tubs off the sleeping area, I'd suggest to just not use them and proceed to the nice-sized walk-in shower.
Personally, neither my wife nor I have ever used the soaker tubs. But we have no complaints on the size of the walk-in (master) shower.
In my own house our walk in shower is 3 x 6' with two controls and two shower heads. That is big enough for two people. I think that at DSV1 and 2 (master) the showers are similar sized but with just one control/shower head.
