Yeah definitely get them into bigger pots. They went dry. Water them good for a couple days and they should perk up.
When you go away for a couple days take a large pepsi bottle, flush it good and fill with water. poke a hole in the cap and insert a 1/4" or 3/8" tube a couple inches in the cap. Turn the bottle upside down and then stick it in the soil. It'll keep the plant hydrated longer. They also sell glass globes that do this same thing.
