It's funny, the house we've been living in for more than 20 years has a separate bathtub and shower in the master bath. I can count the number of times on one hand that we've actually used the bathtub. Besides, when we want to lay back and relax in some hot bubbling water, we just go out to our jacuzzi.
Having just a shower for our Premier room that we've booked is not only no inconvenience for us, it's actually preferred.
Reading is fundamental. It's just that for some, it's more mental than fun.
