Date day Ideas?

I have been working my butt off and finally getting money/time to pay our babysitter and go on a date. I want a long date day half a day or so, typically we just go shop and get dinner.

I wish we could get a hotel but Im not ready to leave the kids overnight without me.

Im trying to think of something creative and different and fun. He doesnt know Im planning something for us but we never get time anymore and I miss him.

2 things to note:

-My husband has IBS bad and needs to be somewhere with bathrooms near by

-Im also pregnant.
