Hotel Sunroute Plaza Shinjuku
http://www.sunroutehotel.jp/htok-eng/index.asp:
which exit do I take from the Shinjuku station to get to the Sunroute Plaza Hotel? South Exit or Sothern Terrace Exit. I presume the latter will be better.
- From Yamanote Line's inner loop (Track 14): Going up via an escalator at the end in the direction of your train, you'll soon find Sothern Terrace Exit.
- From Narita Express (Track 5 or 6): Going up via an escalator and advancing to the left, you'll find Sothern Terrace Exit.
You can ask a station attendant how to get to Hotel Sunroute Plaza Shinjuku.
I guess a taxi will cost around 1,000 yen when the road is not crowded.
As to limousine:
Considering immigration procedures, your limousine will be the last one (for two hotels including Sunroute) which is scheduled to leave at 20:40 from a Bus Stop near Terminal 2 (North side). This limousine then stops at Terminal 2 (South side), Terminal 1 (South Wing) and Terminal 1 (North Wing) within 10 minutes. No reservation is required.
As to PASMO and Suica:
PASMO and Suica are compatible as to e-money systems for fare payment and for shopping.
Anyone of you can use either a PASMO card or a Suica card for a railroad fare between two stations in and around Tokyo within Suica-PASMO area. (One ride can include sections of 4 railroad operators.)
You are all over 12, so each of you can hold an unsigned Suica card for an adult.
As to Seishun 18:
Seishun 18 Kippu is a seasonal set of 5 one-day tickets. The ticket does not cover a fare or a charge for any ride on Express or Limited Express (including Shinkansen) trains. One ticket costs 2,300 yen at average.
Probably it's not so easy for one person to balance 2,300 yen in one day only by trips in Tokyo's urban area.
As to JR East Pass:
Judging from your plan, presumably you can do most of your travel with rides on trains which require fares only, so it's not a case where a JR-East Pass is economical.
