Yes they are a metal portacrib type of crib & they are 40" long. My dd slept in one our last 4 visits at the Swan. Our last visit was her last sleep in one because she's getting too big now. Believe it or not she was over 3 but she is petite and slept in it. Much nicer than a pack n play.
Sometimes they put bumpers on them, make sure to request them since your baby is still under a year old. They also have a light blanket but you may want to bring some receiving blankets of your own.
Also, make sure you check the mattress, on 2 occasions we were given a ripped mattress which made it feel like she was sleeping on the springs. We called down and they brought up a nice thick mattress. Ask for a thick mattress first if you can, they do have them but you really have to request them.
There is no charge for cribs. This part of the S/D's service. But, do request it when you make your reservation or if you've already made one just give them a call back.
