Beach comber or Beached whale

So beach season is quickly approaching. My extra 30 pounds (yes, 30. Thank you not being on adderall and the recent gain from fertility drugs)  that I've gained since August isn't disappearing anytime soon. I've got a family beach trip coming up for easter and would prefer not to look like a beached whale. I don't think the bikini is happening for me this year, at least not in the beginning! Hmmm, so now what?! I've been looking into tankinis, swim dresses, skirts, etc and need some help! Please bear in mind that I'm trying to look 26, not 66. Here are a few options I've been looking at. Let me know your thoughts!
