The upside for Nicaragua seems to be a lesser number of tourists
Nicaragua is very small country in comparison to Ecuador, and it its highlights very concentrated, so the 5 main things you would want to see, will also be popular with tourist, and July-August is a period in which schools are out and people vacation, it will ba close to a peak time as far as tourist go, and this will be concentrated in Leon, Granada, Ometepe, SJDS and Corn Islands. To base a trip on whether there are lost of tourist is self defeating, you are a tourist. But, that is not to say there are lots of tourist either, as Nicaragua is still under the radar IMHO, and as long as you accept the fact tourist go where you want to go, then its no big deal. Paris is touristy, and I could go there every weekend.
The down side is likely the weather, it's cloudy and a little rainy during North American summer
Since when is weather like some clouds and rains from time to time a factor? Not to mention, it is the tropics, and it is actually the prime time to go, as the canopy is very lush, and the landscape very pretty, not brown and dried out like Dry Season, Dec to April. October is bad month for rain, otherwise, the afternoon rains are a welcome respite from the intense heat, and Nicaragua lowlands, and all the placed mentioned above, are hot as hell.
The upside for Ecuador seems to be that it's a compact country? Have you looked at map? You can drive across Nicaragua if a road went coast to coast, in 7 hours.
with varied geography It does have the mountains, but not 2 oceans, and a chain of volcanos to hike from a great town.
nice people but probably more tourists and therefore higher costs
I have never hear that analogy, and it is not correct, Vietnam gets tons of tourist, and is still a great value. The economies and your travel budget dictate what is expensive. Choices of lodging and transport in a well developed tourist country, actually adds to the ease of getting around, and having more choices in your budget,
But it appears the weather is nicer in July and August. I don't think I will visit Galapagos, since it seems extremely expensive, and probably should be a separate trip of its own
True it is a pain to get to, but the highlight of going to Equador, is the Galapagos, and is the ONLY reason I would go to Equador for a vacation.
You seem to have your priorities based on tourist, weather, and a cost. You should not base a trip to a new culture on this soley, IMHO, and go because you want to see, smell, eat, drink, and enjoy a new land.
Also, how will you ever conquer traveling to most the world, with your concerns about about weather, and tourist? Nepal? Nepal? Burma? India? Japan? Amazon? Italy? Iceland?
I have not been to Equador, but your criteria and statements about Nicaragua are not correct, so I imagine your ideas about Equador are incorrect as well, and would post this in the SA TT. I have the Equador LP Guidebook, as I almost went 2 years ago for 10 days, but my travel partner father fell ill, and we canceled the trip. I still plan on going, and unless its snowing, I have little concern about, weather, tourist and my budget, in South America, Latin America. The plane ticket tends to be the cost problem for most people, me included.
Also, the highlight of the Central America region is Guatemala, and this should be a priority, culturally speaking, as far as Mayan culture is concerned, and southern Mexico.
A side trip to Panama? Thats not easy, 2.5 days of busses, or $300 airfare? What about Costa Rica? The most Bio Diverse country in the western hemisphere, besides the Amazon> Its 2 hours bus ride?
