This might be difficult for you to do while being pregnant. I have decorated the bedroom for a special occasions. I made it look like a tropical retreat. I bought a small palm tree, hung little white Christmas lights around the room. I cut up lots of fresh fruits, cheeses, crackers and sparkling grape juice. Other things I included were candles, music, massaging oil, flowers on the dresser. I went to a party store and got those Hawaiian lays and a few other decorations. You could wear a bikini top, with a grass skirt, put a flower in your hair, with no panties on. lol

If you want to do the whole dinner thing you could make Hawaiian shesk-ko-bobs and a Jamacan rice. You could make fruit smoothies for dessert with an unbrella in it. or You could make a birthday sheet cake and make it look like the beach with the ocean. Then get some plastic Hawaiian dancers to put on the cake.
