Pls comment on my schedule to Cuba

Day 1 Fly from Cancun of Mexico to Havana of Cuba, afternoon: Vieja (old town) including Ambos Mundos Room 511-- Museo Hemingways + museums

Day 2: Havana --> Pinar Del Rio City (Cane/ Tabacoo Farms) --> Vinales Valley (Indian picture on the mountain) + Indian Cave --> Havana

Is there any 1 day tour from Cuba Travel agency for Day 2 schedule & how much? How much of a taxi fee for whole day trip?

Day 3 Havana --> Mantan Zas --> Bellamar Cave --> Varadero

Day 4 Varadero --> Havana --> Vedado (New Town) + Museo Hemingways & Cojimar (the village "of the Old Man and the Sea")

Is there any taxi at Cojimar & Mueso Hemingways? Should I hire a taxi for the whole day? How much?

Day 5 Fly from Havana to Mexico?

Is my shedule to Cuba feasible?

Thanks

Wah..if you only have 4 days in Cuba...I suggest you dont sleep overnight in Varadero. It is only a ressort beach which you can find in Thailand.

If you want to feel more about Cuba, stay one night in Vinales or Trinidad.
You will know what is Musics Culture and beautiful landscape in CUBA.

For beach, you can take T3 in Havana to Playa del Este. Enjoy a half day sunshine in order to stay in Varadero.

Moreover, in Varadero, not much Cubano Culture life at night. You can only find them out in some large Hotel which is not really recommended to do.
