I think you will be just fine to make it to a place you can get a new chain and sprockets, this is not an emergency.
I used to get that same problem on my Honda VFR 800 Interceptor 's and I owned 2 for over 45,00 miles each, never had a problem as long as I adjusted the chain with some slack in the tight zone. It will not come out over the sprockets if you adjust slack just under most tense zone. Also consider that when you both sit on the bike and suspension is compressed the chain gets tighter than when checked on center stand. With all the load and two people, you should adjust suspension to put maximum preload on rear shock - that will minimize the chain wear.
The idea is not to overload the transmission pinion bearing because of a too tight chain, that's allot bigger trouble so keep it on the loose side. You probably would have not gotten even half this life out of it if not cleaned and lubed regularly, so don't disregard maintenance.
