We are flying into HND but taking snow bus to Hakuba. No issues there. Its the return journey to NRT that's being the bugger. TA has told us the they are trying "upgrade" from limo bus to "shared limo van?" direct to hotel. Assuming these exist, its certainly suitable but the anecdotal evidence here suggests otherwise. Its cutting it fine certainly, as I still dont have the vouchers etc for the rest of the trip and have work based travel coming later in the week and next week before we go. We will see how it all goes i guess.
The inbound journey from NRT probably would be easier than the outbound by the sounds.
I am certainly getting an email prepared to send to AFTA (for those that don't know they handle ombudsmen type complaints for registered travel agents) regarding the failure to get sorted what we have paid for.
