How do I approach the subject of giving a wedding gift at a destination wedding? - destination wedding thank you gifts

We are a destination wedding and have answers to questions from customers on flights, hotels, transportation. It seems that not many people will be able to come to or are on a tight budget. We expressed our customers that they will be able to understand, and I hope they think about us, our special days. Since we know that is a burden that we should meet somewhere on the invitation that the gift of "necessary" or not needed. How can we include this information does not make anyone uncomfortable, if it is given or will give you not be there for her and we're just happy to be there.
Thank you!
