Recommendation for swim classes for a 5yo

Hello! I’m interested in signing my 5yo daughter up for swim lessons , does any one have experience with classes at the ymca? If so any input on Oakland vs Berkeley ymca? We have done tiny tots at strawberry canyon but I’m having a hard time with the classes at city pools and strawberry canyon selling out so quickly! I’m thinking maybe ymca might be easier to get into lessons since the pool is indoors and lessons run all year?  Also open to private swim lessons if anyone has a recommendation! Thanks for any input:)- Julie
