A party of 7 of us from Barbados stayed at Hampton Inn & Suites - Miami Airport / Blue Lagoon the night before our cruise on one of the carnival liners. The reception staff was very cordial and helpful. While waiting for my room to be ready (just about 15 mins) I was able to enjoy their wonderfully brewed complimentary coffee.
We spent another 2 night after our cruise to do some shopping and were pleased to find out that several shopping centers, restaurants and a supermarket were within walking distance. Yes...Burlington, Publix supermarket which has an excellent deli, Subway, Burger King to name a few. The hotel is also near CVS and Walgreen's pharmacies.
The Hampton Inn shuttle to and from the airport is free and runs every half hour.
We also had free internet access and TV with the usual channels.
Great experience and I'll stay there again.
