Help translate two short phrases

[inquirer]

Hello All,

Could you help me translate the following two phrases:

1. 如方便出发前通次电话. I understand that this is an invitation to call, but the following characters confuse me: 前通次. The exact translation eludes me.

2. 我会记住在一起的夜晚. I will remember the night we spent together. My question is whether the word 夜晚 and the phrase context suggest HOW the night was spent: whether it was an intimate experience or just a party with friends.

Thanks in advance!

如(果)/方便/出发前before depart/通/次/电话.

Please call me before you depart if it's convenient.

2.I think "an intimate experience " is more proper here.

hope it helps.

Thanks a lot!
