Wedding date dilemma

Hey all!


Looking for some advice here…
My partner and I have been discussing wedding plans but have not formally set a date yet. We have been looking into a venue for April next year but have not booked it yet. I am keen to have our wedding in early spring as I am conscious about my age and want to start trying for a baby as soon as we get married so I don’t want to delay our wedding beyond spring next year.
However, my partner’s sister recently got engaged and she has already set a date for her wedding in June next year and has now set a date for her bachelorette party (weekend away) in April, very close to the date we had in mind for our wedding.
I feel that we have been too slow with planning our wedding (due to our circumstances) and now it is limiting us with the dates we can choose.
What is your advice regarding our plans for our wedding? Would it be rude to have our wedding the weekend before or after her bachelorette party? This would of course affect my ability to attend her bachelorette party too.
Unfortunately the venue we’ve been looking at would not have availability until July otherwise (which May clash with some key guests’ availabilities) and alternatives are more expensive…
Any advice would be appreciated!
