Arriving at MIA around 7:15am on Sunday morning, with my next flight being late the following day.

Hoping I can drop my bag off at a hotel prior to the official check in times so that I can explore a little.

Cash wise, places such the Staybridge near the airport are going for a minimum of £96 / $120? or 15k-20k for redemptions.​

I haven't renewed my Ambassador membership so will avoid paying cash for ICs until it suits me better.
Not sure if I could apply a suite upgrade though? Got 2 to use up.

£150-£200 is average if nearer Miami beach.

Redemption wise:
Kimpton Epic for 37k points + $37 amenity fee.
Atwell Suites Bricknell 23k
indigo Bricknell 20k
Kimpton Palomar South Beach 18k
Kimpton Surfcomer 27k
Holiday Inn Miami Beach ocean front 23k + $33 amenity fee
IC Doral 28k

Want somewhere that isn’t too difficult to get between the airport and to see South Beach etc. for the first time. Using public transport, so trains, buses and walking.
A bonus would be somewhere with a lounge so that I can use my lounge access reward.
(Will hit 40 nights with this stay, so 20k points, food vouchers and/or lounge access etc.)
