I always ask for a cot at hotels and I buy local baby food. The quality is regulated across the EU
We just used the hotel travel cot and went to the local supermarket and bought bits for her plus she ate her meals at restaurants etc with us
We also used the travel cot and recently went all inclusive so gave her the bits we thought were okay for her to eat ( not high salt etc) and cut up accordingly for her
We just use the hotels travel cot, we have been all inclusive so I just picked lots of things from the buffet for her to try but also when we went out, just ate off our plates or starters (not kids meals as these are actually normally higher in salt and fat - why they only put chicken nuggets or pizza on kids menus I’ll never know 😅).
We didn't take a travel cot, we got one at the resort. We took some Ella's kitchen pouches (about 7 I think for a 10 night stay) with our 9 month old but he mainly ate what we did. He tried everything and loved it. you'll find something familiar for her I'm sure.
