Cabin vacation with toddler?

JV

Next week we’re renting a cabin on a scenic lake in the mountains. My daughter is 21 months... anyone have any tips? This will be our first vacation with her. My parents are also renting a cabin nearby so we’ll get together for lunch and dinner. There is a lake and we were planning on swimming. Unfortunately the weather looks iffy! I’m so nervous! It’s pretty isolated, no attractions really, just mountains and forests and the lake.
