Most people who marry at Couples are spending their honeymoon there, so I think you would receive either the 30-minute massages as part of the wedding package OR the massages as part of the honeymoon package, but not both.
If you married at one of the resorts and then had a trip to a second resort scheduled (i.e., some people take two weeks, spending one week at the resort at which they marry and then spending a second week at a second resort), then you would be eligible to receive the massages as part of the wedding package at the first resort. At the second resort, you would receive the free massages as part of the honeymoon package and, assuming that you are Romance Rewards members, a second pair of massages as part of the perks offered to repeat guests.
I know everything, and I'm always right (just ask my husband).
We did a vow renewal on our honeymoon and we got the perks for both in addition to the repeaters perks. We didn't actually get all of the repeaters perks but we did get the massages. It wasn't because we didn't qualify though, I think they either forgot or were not very organized.
I would email the wedding coordinator. She is very helpful and will know for sure.
