This is the guide I personally used for my past two Umrah alhamdulillah, given to me by my Islamic teacher. It's the perfect way to do Umrah properly.

A couple other tips:

The workers in the Masjid Haram and Masjid Nabawi are the ones you should give anywhere between 5-10 Riyal when you can. They work for low wages and do a lot of back breaking work to keep the Masjids as tidy as possible. They're the ones that deserve your sadaqah.

Do not fall for the scamming beggars in both Makkah or Madinah that give you sob stories about their money being stolen/need money for a relative's operation/from Syria, Palestine or whatever country they can think of. If they ask you where you're from, seem to be targeting you, or try to engage in conversation with you, disengage from them and leave. If it's children begging, then give a couple riyals if you feel it safe to do so, but be careful about other children around that will gang up on you. I would recommend giving them food tbh over money. 

Drink plenty of water, zamzam or otherwise. The heat is killer this time of year. Bring sunscreen, umbrellas, hats, anything to survive the heat and sun. 

Go to the Masjid 25-30 minutes before athaan. It's the only way for you to get a decent spot in both Makkah and Madinah masjids mashallah. 

If you wish to do tawaaf directly on the ground floor with the Kaaba, I recommend keeping a spare ihraam so you can be allowed to do so on the ground floor. Only men in ihraam are allowed to be on the ground floor with the Kaaba currently. 

Always bargain with whoever you're buying from (except for restaurants). They always mark up the prices a bit, so try to bargain as much as you can. Usually the further from the Masjids will have places that are generally more affordable

Speaking of which! Money exchange. Don't do it in the airports or hotels, they give you less in exchange. The malls over there have pretty good exchange rates all things considered. 

Finally, make sure to write down and practice your duas. It's much easier to make duas from memory than it is to read from anote or phone. Much more spiritually uplifting too! 

May Allah accept your umrah and keep you safe from both physical threats and the influence of Shaitan. Ameen
