My wife and I (mid 50’s) will be in San Diego around the first week of October. She will be attending a conference at the Convention Center part of the week and I will be enjoying the city the entire week. We were San Diego for the same reason about 5 years ago. We stayed at the Omni which was a good base for me with a convenient trolley stop and the Gas Lamp area very near, and she had a short walk to the Convention Center. This year the conference headquarters is the Manchester Grand Hyatt. How would you compare the two hotels for the hotels themselves, being close to things to do and getting to the Convention Center? Her convenience to the Convention Center is the highest priority. Are there other hotels in that area that you would recommend instead? Thanks in advance for your advice.
