Even in areas (like NS) that have nap/rest guidelines, they are very flexible and unlikely to require you to change the way you do things. I must provide a place to sleep for all children under school age (which is 5 here), and have a minimum 30min rest time in my program. If playpens are used for babies, they must be approved as a 'portable crib'. But playpens sold with bassinets (like Graco) usually meet the certification. My sleep room for toddlers has mattresses on the floor and a 2h nap time. I have fold up mats for preschoolers that never come out-their quiet time is colouring and puzzles. I bring them out for days they need to lie down, and we have a movie.
