3 month old to little for small blow up pool?

We will be going on a 4 day beach vacation next month and my daughter will be 3 months then.. I have a little baby tent for her and thought about getting a small

blow up pool to blow up and sit her in every now and then while at the beach since she will be to small for the ocean. She LOVES bath time so I'm not worried about her not liking it.. Just wasn't sure if a 3 month old was to little for a pool?

( We will be holding her the whole time she would be in the pool. )
