Things to do in Panama City region, next month

I have a week to explore the county. Has anyone taken these trips or know lower prices available? Is there a cheaper alternative DIY?
The Panama Canal Railway, cost $38.52 for 8 hours.
Hop On Hop Off 72 Hour Pass- Panama City Sightseeing, cost $46.88, 3 days.
Horseback Riding and Hot Springs, cost $ 25.00, I do not know the length of this activity.
Hiking at 3 Waterfalls - Santa Fe National Park, $110.00,  I do not know the length of this activity.
Camino de Cruces-Trekking Tour, a historical walk, $111.25 8 hours.
A good lower price real massage therapist, masseuse? Should be less than $60 per hour.

    My next request, were is a good place to dance and hangout with fun people? So far big, city people in other countries have been a little boring in the evening. Discos have a lot of people sitting around drinking and looking at each other. Very little to no dancing and you likely get a strange look and polite no if you ask them to dance.  In the smaller towns and the further away from tourist areas/gringo-land, it seems to be more people willing to dance with a stranger.

Hopefully, in Panama my evening experience will be different.

if you want to party go to colombia

I found that the best things to do in PC were free or almost free:

-Hike the Cinta Costera
-Explore Casco Viejo
-Explore the neighborhoods of PC on foot to see more sights up close
-The canal observation deck is free for all residents of Panama
-Ride the new Metro train for 35 cents and explore El Canrejo
-The On-Off Bus is $15 for Pensionado Visa residents; it is a good way to see the city in a hurry
