What boogie board or toddler board fits onto the Mac Rally Twin?

[catfeet]

Well, the title says it all, lol. I've got a RT that will probably be going, or the combo of a Triumph and a Combi, and 3 kids. We're going to New Orleans in March, and I'd just as soon not bring the double and a single. DH refuses to travel with our Valco Twin, and now that we've got 3 kids and the associated carseats & stuff, I can't say as I blame him. Anyway, I need a boogie board or hitchhiker type board to fit onto either a RT or Triumph.

What's avalible that fits those strollers?

TIA,
Ann
