Suggestions on adding people to an already booked trip?

[Aflyingbuttress]

We're booked at CBR from Oct 29-Nov 6. Currently it's just me, my husband and our daughter in one room. My sister and her fiancé are interested in joining us. Are there any options for us either changing our reservations or them coming on a promotion that would save them money. I'd be happy to continue paying what we're currently paying and have them just make up the difference if there's a way to save money by changing things around as opposed to them getting a whole separate trip cost (if that makes sense).

Any thoughts?

We have added two extra people to our trips several times, some times we had to pay an extra $5 fee for the adult but my husband and I were staying in a Fort Wilderness cabin that holds 6. If your room holds 5 you may be able to add them.
