Eloping without a reception

FH and I want to elope somewhere tropical just the 2 of us then send out announcements letting family and friends know we’re married. It’ll be my 2nd wedding, his 1st. We don’t want a party afterwards, instead we want to wait til a milestone like our 10 or 15 year wedding anniversary and just throw a nice anniversary party instead. It’s not only for financial reasons - neither of us like to dance or be the center of attention. We want the elopement to be Sandals or something similar so there’ll still be flowers, a boutonnière, photos, etc. Has anyone done this? A reception isn’t required when we get home, is it? If it were, wouldn’t people forgo the elopement and just have a 20-guest wedding? We’re already in our 30s and would rather spend the weeks after our elopement on the honeymoon, spending time together and having adventures.
