Sure! There's a couple of singles available, but they're the most expensive rooms, so depending on Padme's current income and willingness to help around the Hotel she may prefer something else. There's also some cheaper dorms, if she doesn't mind sharing, or for the least expensive option Anton can make up a bed on the floor of Anakin and Obi-Wan's room for a small linens surcharge. (And then she can kick one of them onto the floor instead.)
