my mil is planning our rehearsal dinner at the wilderness lodge either the whispering canyon or artist point for 15, still waiting for additional info from my em & the restaurants. but no private room there. we plan on doing a hayride afterwards. so the rd is western, wilderness themed.
were also hosting a seperate welcome dinner on sunday for all our guests at a private room at dtd's rainforest cafe for 60. were having the cha chas menu $38/adult $10.50/child & the theme is rainforest & animals.
for 70 your best bet is talking to your em about what locations can work for you, plus it can get moderate to expensive. for a private room dinner your best bet would be at one of the convention centers yc, bwi, gf or ariels at the bc, an illuminations dessert party outside or the living seas lounge at epcot. the california grill napa room has a 50 person limit & the attic at the bwi has a 60 person limit & jiko only holds 40. you might also check out some of the dtd locations like rainforest cafe, disney quest, etc or the swan. as for open nonprivate room restaurants check out ohanas, one of the buffets like chef mickeys which is like $20pp or one of the dinner shows hoop dee do revue or the poly luau which can accomodate large groups.
best of luck with your plans.
