Infant abroad - any tips?!

We’ve booked a holiday abroad for when my girl is 7 months. It’s a resort but with bus links to the old town of the capital, so we plan to do 1-2 days of exploring but we’ll mainly relax in and around the resort. My husband said it’s pointless to take the buggy because it’s all cobbled streets and steps and a stress to carry around. He just wants to take the body baby carrier! The hotel has a cot so we’ve ruled out taking our own too.

Any experienced baby holiday goers here? Just wondering if it’s a mistake to not take the buggy! Any other tips with taking a 7 month old abroad would also be appreciated 😁
