Having a destination wedding is your choice, however, you are aware when making this decision that most people will be unable to attend. Knowing this, you should never expect or accept a gift from anyone.
Having a reception when you get home is just saying, " We really didn't care that you couldn't make it to our wedding, but give us a gift anyway!"
You should have a destination wedding if that is what you want and enjoy every minute of your beautiful day. But do not go asking for gifts, which is what you will be doing by having a reception. That is cheap, rude and selfish.
