Congratulations on reuniting with your love! Have fun with your planning!
Really depends on the relationship with your sister. If you have a good relationship, she will understand it automatically that this is an intimate meal for 2.
If you think she needs some instruction, better give it to her as soon as possible, be open and clear about you love her being at the wedding and having a family vacation, but at times X, Y and Z, you will split ways for certain events. That's time she can spend time with her own family.
