My parents contributed a good bit of money toward my wedding. I was thinking, since it's in Jamaica....paying for their day trip to dunn's river falls and dolphin cove and I was going to give them a parents photo album. I'm still trying to think of other ideas. Maybe you could pay for their way to the activities that may cost more. Or sometimes they even have different packages like for engagement, or renewal of vows where you can arrange a really private dinner, etc. Maybe they also just arrange very private dinners. You may be able to contact the wedding coordinator and ask if there is any such service at the hotel. Good luck! I'm sure your parents will love whatever you give them.
