For those with Goodnights points - I looked on the site and couldn't find them referenced so I wrote the customer service an email this is the answer:
Thanks for your e-mail about the HUGGIES® Rewards program from HUGGIES®
diapers.
In response to your inquiry, the proof-of purchase points from
GOODNITES® disposable absorbent underpants will be honored for the HUGGIES
Rewards program. This product is not referenced in the HUGGIES Rewards
program because we recently removed the proof-of-purchase points from our
packages of GOODNITES underpants. However, we are happy to offer you
this opportunity to use your accumulated points.
Thanks again for visiting our web site and for taking the time to
contact us.
I have enough for the stargazer set and more! Thanks for the tip.
