30th Anniversary In May

I am planning my own 30th wedding anniversary party ( is this proper?).
It is mid May and I am leaning towards just having my children and their significant others for a week-end event, possibly an oceanfront Inn in NE. Does anyone have any ideas for Inns..I would like a place with Activities for everyone so that we can have a fun filled week-end together. Has to have views, Great Food and once again Activities, Music, Dancing etc.
If anyone has any suggestions, or has already done this for themselves, please help!
Thank you so much!
