Here are some notes
Iberostar Parque Central hotel was excellent, but needs 220 plug converter in addition to a 2 prong plug for electricity
Bring hat, sunglasses, sunscreen, wipies, battery backup for phones, ALARM CLOCK, and at least 2 shirts per day, sometimes 3 shirts
Van Dam StreetSmart Map was very good resource, but hotel has very good free maps
10% tips are standard
Bring Euros as US Dollar will get a 10% penalty
I personally kept all my cash in a zipper case that was not in my pocket and only kept about $10-15 in all $1 cuban pesos in my pocket.
Transportation options are many
Bicitaxi is fine to go a few blocks in Old Havana especially when it is hot and you are tired of walking
Cocotaxi is a lot of fun and can go anywhere much faster than a bike
Traditional yellow cabs with A/C are easy to get at all hotels
Classic car rides are $30 per hour and are a must to drive the Malecon with the top down, there are dozens of them at Parque central outside the hotel
Paseo del Prado is a nice walk to the ocean especially on Sunday with art vendors
Fabrica de Arte Cubano FAC – 8pm to 3am, lines after 10pm (Thursday to Sunday only) is Hip Nighttime variety of shows, music, dancing, drinks, design, theater and the IN PLACE to be at night
I did not see the Tropicana show but would have if I had more time in Cuba
Most museums are closed on monday
National Museum of Fine Arts was as good as any in the US and had A/C indoors
Museum of the Revolution and Granma Memoria was interesting, but all in Spanish and would be better with a guide. The lemonade in the cafe on the first floor that was made to order was incredible.
La Bodeguita del Medio - birthplace of the mojito is a must visit - make sure to write some graffiti on the wall - ask for a black pen
Calle Obispo is a super busy street with shops, restaurants and tons of locals
Floridita bar - home to the daiquiri and a must visit
Sloppy Joes is a super clean restaurant and bar and a safe choice
Plaza de Armas - super interesting outdoor flea market where you can buy some interesting things like cuban ration books, old pictures, casino chips, antique watches, art, Russian pins, cameras, etc.
