Miami "daycation" hotels?

[MightyMike]

Our return flights got moved to 8pm. We will need to fill some time from disembarkation until evening. Are there any Miami hotels with a good pool that would allow us to camp out there for the day? We would need them to store our luggage. Ideally, it would be near the Metromover so we can venture out a little too. If so, how much does something like this cost?
