In Derby the only hotel I’ve come across SPs working out of is the one from the same chain as the very popular one by the train station in Nottingham, but no where near as active.
Pride Park is probably a 5 minute taxi journey from the apartments opposite the nice burger place that are extremely popular with SPs - I suspect you would have better luck there.
Apologies for being a bit cryptic, abiding by the rules and trying to use some discretion.
