yes, but the OP here isn't coming that weekend. We actually arrived in the Boston suburbs (Metrowest) on Marathon Monday (bad planning on our part) and our hotel was very fairly priced. Truly expected it to be worse and full of runners.

Easy to get to the subway, too, from there. To the airport or into the city for touring.

Drove by there this past weekend, as we journeyed from a Deer Island walk to the Market Basket Mothership. The Mrs. was surprised to see all the hotels there, more surprised when I told her it's where folks visiting Boston on a budget stay. "But it's so far away and not pretty and hard to get to town from here" she said. I nodded in agreement. October is expensive due to Leaf peeping and college Homecomings and conventions.

You really SHOULD see the city, it's vibrant and alive and pretty darn special. We were there 2 weekends ago for 4 days and it was amazing. Clean, fewer homeless than we expected, the subways were running on time and are cheap, and we walked and walked all over the place. Ignore what you see on curated TV and websites and ask people who have been there

Some Quincy hotels have dedicated shuttles for their guests to the airport and cruiseport. Ask them before you pay for an alternative

The Omni Parker House is right on the Freedom Trail and is one of the most historic hotels in the country. The Hyatt, assuming it's the one downtown, is fine, but nothing special and the neighborhood is awfully quiet at night

As long as HE is paying, then more power to him. I was going to suggest you give him the simple directions to take public transit into Manhattan, and then discuss the steps from there to NJ afterwards

I'd expect the starboard side to have more sun, which might be nice in the North Atlantic

What is the question?

I am not sure anyone has made a chart. And if we did have the info, do you really need info on every tender port in both countries? Which ports are YOU going to and what time of year is the trip?

5 trips to Iceland so far and the only 2 times I've needed cash were for a pay toilet, where there was a basket and a sign asking for cash in 5 or 6 different currencies (AUD wasn't one of them) and once when we bought tomatoes from a tray in front of someone's house and there was an honor box. We use our credit card for everything, we have one with no foreign fees which is great, but even if you have to pay 2-3% extra, the convenience is worth it and not worrying about adding funds or being stuck with cash at the end of the trip (we unloaded the rest of our ISK on unnecessary stuff at the airport and didn't get any on our last visit)

To confirm, it's too late in the season for much chance of Northern Lights. It just doesn't get dark enough long enough to see anything. Checking out some Golden Circle sites or visiting the Reykjanes Peninsula would be my suggestions

Jokulsarlon is amazing. But a one day trip to there and back is SO much bus time! And you pass by glaciers and national parks and waterfalls and other gorgeous things There are great South Coast 1 day tours that don't drive all the way to the lagoon that I would recommend over a Jokulsarlon trip. And the Golden Circle is terrific.

You can Uber anywhere. You can also take MBTA Commuter Rail or a Ferry boat from Boston to Salem. You can walk as little or as much as you want in Salem. Which museum are you referring to? Salem has more than one! The PEM is the best one, IMHO

You climb down 2 or 3 steps and climb up 2 or 3 steps. They will help with luggage if you need assistance.
