Help me decipher baby vacation wakes

Hello! Baby is about 7.5 months old. Currently on vacation with a 4 hour time change. I was expecting some struggles - I have a hard time adjusting to the time difference! But she’s been having night wakings the last few nights. Our flight was a night one so sleep was messy that day/night. Since then she’s been waking around 3am and is hard to get back down. I’ve tried nursing and she will go back to sleep but then wakes an hour later and doesn’t really go back to sleep.

Last night she was awake at 10pm then every hour or so after that.

She is sleep trained but we are in a hotel room with my husband and other kids so letting her cry isn’t really an option.

She was on 3/3.5/3.5 and I’ve been sticking to those wake windows relatively closely. Naps have been on the beach and some in her pack n play.

For a few nights her last wake window was stretched beyond 4 just due to slow restaurants etc.

I don’t mind her waking early. Like I said I know time zone changes are tough but I’d like to try and figure out these wakings if we can.

Does it sound like overtired? Undertired? Or am I screwed and just survive the next 3 nights….
