As long as you have an adult listed in each room, should be fine. I know you are allowed to put under 18's in a connecting room with the parents in the other room, but since you are in one & your spouse in the other (officially, according to the paperwork), should be able to bring 2 per stateroom.
I'm doing something similar on my upcoming cruise. DH & younger DD want DBP, but I don't & older DD can't (health reasons). We're in connecting rooms also, so we just switched me & younger DD so that we didn't have to call about getting the refreshment packages with the DBP for just one person in each cabin. Plus, I may want one or 2 drinks or glasses of wine, which I will pay for, but would not get my money's worth on the bigger package. Didn't want to say I couldn't drink for health reasons, then get caught drinking. Probably unlikely that I would be, but don't want to mess with the system.
pack them in 2 separate carry ons. The security will take 2 bottles out of a carryon that contains 4. I do not know if they would take the time to look at your set sail pass to see you have 2 separate reservations.
