yea, my sister in law does money and I thought maybe since they are older they'd like that. having $1 and $2 coins adds more variety, but will add up quick, especially since Pennies are no longer in use.
What about travel games since you will be away? My kids love getting new card games that are based on board games, and the year I got them travel scrabble and connect 4 was a huge hit....and now that I think about it I think that was a part of Easter.... That's something else I've done too, baskets themed on family game night or family movie night. Oh and I forgot that's usually when they get their new water bottle too.
