Thanks for all your advice so far. Some updates, both families are coming into Haneda but on different days/times.

- Looking for transport from Haneda to Asakusa area for hotel with multiple pieces of luggage per person.
- Would airport limo options be better than train with luggage?
- E-sim vs. Portable wifi- any suggestions of plans/companies/discounts?
- Suggestions of great places to shop, eat or visit?
- Tokyo Sea - any tips? where to buy tickets, days to visit, rides, restaurants, etc

Many thanks!
